## How do you calculate voltage drop in a series circuit?

To calculate voltage drop, E, across a component, you need to know the resistance of the component and the current thru it. Ohm’s Law is E=I⋅R , which tells us to then multiply I by R . E is the voltage across the component also known as voltage drop.

### What will happen if one light bulb is removed from a series circuit?

When one light bulb is removed from the series circuit, the other two light bulbs go out. When one part of the series circuit is removed, the circuit is “open”; the other parts do not receive electric energy.

**How do the ∆ V values across each individual bulb compare to the voltage of the battery equation?**

The light bulbs are identical so they have the same resistance value. Thus, the voltage drop across a single bulb will be the same for any one of the bulbs. And the voltage drop across two bulbs or three bulbs will be greater than the voltage drop across a single bulb.

**What is the formula of voltage drop?**

A current of 9A flows through a circuit that carries a resistance of 10 Ω. Determine the voltage drop across the circuit. V= 90 v….Given:

## How is opening the switch like removing a light bulb from the circuit?

How is opening the switch like removing a light bulb from the circuit? It breaks (opens) the electrical path (circuit), so current cannot flow, and the bulbs do not light up.

### Is voltage added in series?

Remember the voltage increases when batteries are in series, but with batteries in parallel this is not the case. When two or more batteries are placed in parallel, the voltage in the circuit is the same as each individual battery. When batteries are connected in series, the voltage increases.

**Can you measure voltage in series?**

We measure voltages in a circuit with a voltmeter . The voltmeter is connected in parallel with the component.

**How do you calculate the potential difference across a light bulb?**

force ε: the increase in potential energy per unit charge provided by the chemical reactions in the battery. And the voltage difference across the light bulb is: ∆V = I R = (0.06 A)(20 Ω) = 1.2 V ▪If we measure the voltage difference across the battery or the light bulb, we will get 1.2 V.

## How do you calculate electric pressure?

P=VXI. P = V X I . Here P is power in watts. V is voltage in volts.

### Can you connect batteries of different voltages in series?

Connecting batteries of different voltages in series In theory, a 6 volt 5 Ah battery and a 12 volt 5 Ah battery connected in series will give a supply of 18 volts (6 volts + 12 volts) and 5 Ah. A 6 volt battery is often three 2 volt cells and a 12 volt battery is usually six 2 volt cells.

**How does ohm’s law affect electrical circuits?**

Solution: Ohm’s law tells us that when more voltage establishes across a circuit then a higher current would flow through the resistors in the circuit like electric heaters, light bulbs, and so on. More current can cause damage or failure to the household appliances. For example, a light bulb with resistance

**Can a 6 volt 3Ah battery be used with a 5AH battery?**

In theory a 6 volt 3 Ah battery and a 6 volt 5 Ah battery connected in series would give a supply of 12 volts 3 Ah (the capacity of the weaker battery always restricts the circuit) and if you did so it would work and nothing would explode (to start with).

## What is the difference between 6 volt and 12 volt batteries?

The reality is that no 6 volt battery is exactly 6 volts and no 12 volt battery is exactly 12 volts. Individual cell voltages differ, even with batteries of the same brand and manufacturer. A 6 volt battery might have a cell voltage of 2.2 volts and a 12 volt battery might have a cell voltage of 2.1 volts.
