Circuit 4 is correct
it is ze fourwa
Thank you, I understand.
To determine which circuit will have the greatest electric current, we need to use Ohm's Law, which states that the electric current is equal to the voltage divided by the resistance (I = V/R).
Let's calculate the electric currents for each circuit using the formula mentioned above:
For Circuit 1:
Resistance (R) = 0.5 ohms
Voltage (V) = 20 V
Electric Current (I) = V/R = 20/0.5 = 40 amperes (A)
For Circuit 2:
Resistance (R) = 0.5 ohms
Voltage (V) = 40 V
Electric Current (I) = V/R = 40/0.5 = 80 A
For Circuit 3:
Resistance (R) = 0.25 ohms
Voltage (V) = 40 V
Electric Current (I) = V/R = 40/0.25 = 160 A
For Circuit 4:
Resistance (R) = 0.25 ohms
Voltage (V) = 60 V
Electric Current (I) = V/R = 60/0.25 = 240 A
Comparing the electric currents of all four circuits, we can see that Circuit 4 has the greatest electric current with a value of 240 amperes (A).
