Question

A 24 volt battery is connected to a circuit with a 4- light bulbs that are connected in series. Resistance of each light bulb is 3 Ohms, a) What will be the current in the circuit

Answer 1

Current = 2 amps

Step-by-step explanation:

Remark

The voltage of the circuit is 24 volts.

The Resistance Series circuit is

• Rt = B1 + B2 + B3 + B4
• B1 = B2 = B3 = B4 = 3 ohms
• Rt = 4*3 ohms = 12 ohms (each bulb has a resistance of 3 ohms each and there are four of them)

Givens

E = 24 volts

R = 12 ohms

Formula

E = I * R where

• E = voltage
• R = resistance
• I = Current

Solution

24 volts = 12 * I Divide by 12

24/12 = I

I = 2 amperes.
