Circuit Resistance (ohms) Voltage (V)
1 0.5 20
2 0.5 40
3 0.25 40
4 0.25 60
Which circuit will have the greates electric current?
To determine which circuit will have the greatest electric current, we can use Ohm's Law, which states that the electric current (I) is equal to the voltage (V) divided by the resistance (R) (I = V/R).
Let's calculate the electric current for each circuit:
Circuit 1: I = 20V / 0.5Ω = 40A
Circuit 2: I = 40V / 0.5Ω = 80A
Circuit 3: I = 40V / 0.25Ω = 160A
Circuit 4: I = 60V / 0.25Ω = 240A
Therefore, Circuit 4 will have the greatest electric current with 240 Amperes.
