Answer:
Current = 2 amps
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.
