When three resistors each of resistance 30 ohms are connected in parallel then effective resistance is?

Three Resistances, of Which Two Are Equal When Connected in Series Have an Effective Resistance of 30 Ohms. When the Three Resistances Are Connected in Parallel, the Effective Resistances is 3 Ohms.

How do you find the resistance of a resistor in a circuit?

This formula tells you that your resistance is always equal to your voltage divided by the current. You can also say that your voltage is equal to your current multiplied by your resistance, or V = IR in equation form, with R = V / I. Your circuit has a voltage of 50 Volts.

What is the current through 30 ohm resistor in the given circuit?

⇒I30=0.2 amps. Hence the amount of current flowing through the 5-ohm is 1.2 amps, through 10-ohm is 0.6 amps and through 30-ohm is 0.2 amps.

How do you calculate resistors in a circuit?

If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm’s Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.

How many resistors are there in a 60V circuit?

Three resistors with values 30 ohms, 15 ohms, and 10 ohms are connected in parallel across a 60V battery. what is the current through each branch of the circuit, equivalent resistance of the circuit and the total current of the circuit? This looks like a school assignment question. You should have already learnerd the basics of Ohms Law.

What is the potential difference of a 30 ohm resistor?

Three resistors having 10, 20, and 30 ohm resistance are connected in series with a potential difference of 60V. What is the current through the 30 ohm resistor? Three resistors having 10, 20, and 30 ohm resistance are connected in series with a potential difference of 60V.

How many resistors are connected in parallel to a 9v battery?

Three resistors of 10, 20 and 30 ohms are connected in parallel to a 9V battery. Calculate: ( For parallel combination of resistor, potential difference across each resistor is same.

What is the current through all the resistors in this circuit?

In your case 60 Ohms. The current through all the resistors will be the same. 60 Volts / 60 Ohms is 1 Amp. So that is the current through all of the resistors. In this series connection of resistances, the current will be the same in all three resistors. The total resistance is 60 ohms and the applied voltage is 60 volts.
