Given information
It is given that for an electric device initially drawing a current of 5.6A working at 240V first its voltage is dropped by 15% keeping resistance constant and then resistance is dropped by 15% keeping voltage constant
Step-by-step explanation
Step 1.
The Ohm’s law tells that the ratio of voltage drop (V) and the current (I) passing through a resistance (R) is ideally constant which is equal to the value of that resistance itself, i.e
V=IR
