Answer:

Step-by-step explanation:

I=0.8A

P.D=20V

R=?

R=VI

=20X0.8=16

THEREFORE RESISTANCE IS 16 OHMS

The value of the resistance is 25 Ω

Step-by-step explanation:

Given data

  • The current flowing through a resistor is 0.8 A, Means

        Current (I) = 0.8 A

  • A potential difference across resistance 20 V is applied. Means

        Voltage (V) = 20 V

  • Let Resistance = R = Unknown
  • From Ohm's Law, we know the relation between voltage, current and resistance is that

        Voltage = Current × Resistance

  • On putting respective value in above equation, we get

        20 = 0.8 × R

        On solving

       R = 25 Ω = This is value of resistance.
