Question

When a 40V battery is connected to across an unknown resistor there is a current of 100 mA in the
circuit. Find the value of the resistance of the resistor.

a. 5000Ω b. 800Ω c. 0.8 Ω d. none of these.

Answer 1

Explanation:

ans should be none of the above

Answer 2

Answer:

Non Of These!!!

Explanation:

v= ir  

40 = 10 × r ( one Milli ampere = 0.1 ampere so, 100ma = 10 ampere )

r = 40/10 = 4 ohm
