Question

Electric current flowing through a circuit is inversely proportional to resistance.
When the resistance is 2 ohms, current is 3 amperes. Find the following.
a. The resistance when the current flow is 0.5, 1.2 and 2 amperes respectively
h The current flow in a circuit when the resistance is 1.2, 2.4 and 30 ohms respectiv​

Answer 1

Answer:

The circuit is in parallel arrangement hence it's voltage doesn't divides at its components-

From ohm's law,

V=IR

V= 2*3

V=6 volts

Now, I=0.5 amperes

V=6 volts

V=IR

R=6/0.5

R=12 ohm

by applying the same process you can solve all questions below.. and yes truly I don't want a brainliest mark! I have taught you a way of solving....
