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 using this formula:
For Circuit 1: I = 20 V / 0.5 ohms = 40 A.
For Circuit 2: I = 40 V / 0.5 ohms = 80 A.
For Circuit 3: I = 40 V / 0.25 ohms = 160 A.
For Circuit 4: I = 60 V / 0.25 ohms = 240 A.
Therefore, Circuit 4 will have the greatest electric current, with a value of 240 A.
