Question

The current passing through a resistor in a circuit is 0.01 A. When the voltage across the same resistor is 5 V. What current passes through this resistor when the voltage across it is 7.5 V ?

a. 1.25 A
b. 0.125 A
c. 1.5 A
d. 0.0125 A​

Answer 1

Answer:

Current (I) = 0.01 A

Voltage (V) = 5 V

Resistance (R) = V = IR

= 5 = 0.01R

= 500 ohm = R

Through this same resistor, if 7.5 V passes, the new current will be = V = IR

= 7.5 = 500I

= 0.015 A = I

I hope this helps.
