Respuesta :
the voltage required in the given circuit is 80 volts.
The given parameters;
- quantity of current flowing in the circuit, I = 4 amperes
- resistance of the circuit, r = 20 ohms
The voltage required in the given circuit is calculated from ohms law;
V = Ir
where;
V is the required voltage
Substitute the given parameters and solve for voltage;
V = 4 x 20
V = 80 volts
Thus, the voltage required in the given circuit is 80 volts.
