Question
What is the total current in a circuit consisting of six 100-watt lamps connected in parallel to a 120-volt source?
A) 5 A
B) 20 A
C) 600 A
D) 12 000 A
Solution
To find the total current in a circuit, we first need to find the current for one lamp and then multiply it by the number of lamps.
Step 1: We know that Power (P) = Voltage (V) * Current (I). We can rearrange this formula to find the current: I = P / V.
Step 2: Substitute the given values into the formula. The power of one lamp is 100 watts and the voltage is 120 volts. So, I = 100W / 120V = 0.833A. This is the current for one lamp.
Step 3: Since there are six lamps connected in parallel, the total current is 6 * 0.833A = 5A.
So, the answer is A: 5A.
