Resistance of an electrical instrument is 200 ohm and it can bear a maximum current of 0.1 ampere. If someone wants to connect it to a DC source of 1 ampere find the resistance to be connected in parallel.

Answer:
Resistance = 200
Current = 0.1 A
so Potential difference V = IR
V = 20 volts.
Now this should be the potential difference for the instrument to work without short circuit.
current = 1A
Voltage = 20
so resistance R = V/ I
R = 20 ohm.
Hope it helps..

Answer:
Explanation:
V in circuit = R×I1
=200×1/10=20 V
R=V/I2
=20 ohm
