Answer :
The current required when voltage increase to 75v is 1.5A.
What is voltage and current?
Voltage is the force exerted by the power source of an electrical circuit to move charged electrons (current) through a conducting loop, allowing them to do work such as lighting a lamp.
A stream of charged particles, such as electrons or ions, traveling through an electrical conductor or space is referred to as an electric current.
What is the relationship between current, voltage and resistance?
Ohm's Law expresses the relationship between current, voltage, and resistance. This asserts that if the temperature is constant, the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit.
Voltage = Current * Resistance
According to formula for resistive circuit,
V = I × R
50= 1×R
R = 50 ohm
So after applying 75 Volt the current will be,
I = 75/50= 1.5 Amps
The current required when voltage increase to 75v is 1.5A.
