Three 4Ω resistors connected in parallel have a potential difference of 16 V applied across them. What is the total current in the circuit?
Answer Details
When resistors are connected in parallel, the voltage across each resistor is the same, while the total current through the circuit is the sum of the current through each resistor.
In this case, we have three 4Ω resistors connected in parallel, with a potential difference of 16 V applied across them.
Using Ohm's Law, we can calculate the current through one resistor as I = V/R, where V is the voltage across the resistor, and R is the resistance of the resistor.
For each of the three resistors, the current through them would be I = 16 V / 4 Ω = 4 A.
Since the resistors are connected in parallel, the total current through the circuit is the sum of the current through each resistor, which is 4 A + 4 A + 4 A = 12 A.
Therefore, the total current in the circuit is 12 A. Answer is correct.
