What will happen if there is no resistance in a circuit?

If there really were no resistance in the circuit, the electrons would go around the circuit, and arrive back at the beginning of the circuit with as much energy as the potential difference (the voltage). That final energy is usually what is dissipated as heat or other types of energy by the circuit.

What happens if there is no resistor?

a) If there is no resistor in the circuit ( as in , if you completely remove the resistor) , then there will be no current flowing in the circuit. However, there will be a voltage at the 2 terminal points where the removed resistor used to be.

What happens if a circuit is open or not complete?

An open circuit is an incomplete loop, where the loop is broken at a particular point and electricity can’t flow at all. And, finally, a short circuit is where there’s a complete loop, but electricity is flowing in a way that it isn’t supposed to, usually following an easier route and draining the battery.

What does no resistance mean?

Resistance, symbolized by the (Ω) symbol and measured in Ohms, is a measurement of how well a current can travel through a circuit or a given path. A circuit with no resistance (0) would indicate a complete circuit, or one that has no short.

What does a circuit need to be complete?

A circuit is a complete path around which electricity can flow. It must include a source of electricity, such as a battery. Materials that allow electric current to pass through them easily, called conductors, can be used to link the positive and negative ends of a battery, creating a circuit.

Why is a complete circuit needed for current to flow?

The wires in a circuit carry the electric current to various parts of an electrical or electronic system. For electrons to do their job in producing light, there must be a complete circuit so they can flow through the light bulb and then back out.

Is resistance necessary for current flow?

Resistance prevents current from flowing. If there’s zero resistance, as in some kinds of short circuits, the current will flow in the wire without any losses. The basic rule is Ohm’s Law: If is non-zero, and is zero, then the current will be infinite.

Will current flow if resistance is zero?

When the resistance in any circuit is equal to zero then the current passing through that circuit will be infinite.

How do you find current without resistance?

Start with current and voltage instead. If you don’t know the individual resistance values, you can rely on Ohm’s Law instead: V = IR, or voltage = current x resistance. The first step is to find the circuit’s current and total voltage: The current of a series circuit is the same at all points on the circuit.

In that cause you would have a short circuit. Well no resistance and no resistor are 2 completely different scenarios. a) If there is no resistor in the circuit ( as in , if you completely remove the resistor) , then there will be no current flowing in the circuit.

What happens when you connect a short circuit to a battery?

Ideally, if there is no resistance ,i.e, short circuit is connected across an dc source, infinite current will flow as I=V/R, and R=0. Practically, if you connect a wire directly across a battery, it will start heating. Resistance of short wire is in the range of Ohms which is very less as compare to resistors.

Does current flow through a wire with a resistor?

Short answer yes. The current will flow through the wire. We ignore this when there is a resistor because the resistance in the resistor is much higher than through the wire. Long answer.

What happens if you draw too much current from a battery?

If you try to draw too much current from a small battery or power supply the voltage will be reduced. We have a voltage source and a resistance and when a closed circuit is formed a current will flow. Increase the resistance and less current will flow given the same voltage.
