1.

three resistances 2ohm ,3ohm,4ohm are connected in parallel. the ratio of currents passing through them when a potential difference is applied across its ends will be

Answer»

In Parallel connections Voltage across common points is same

Taking V as the potential applied

The Current through 2 Ohm resistor is V/2

The Current through 3 Ohm resistor is V/3

The Current through4 Ohm resistor is V/4

Hence the ratio oth the current in this case is 1/2 : 1/3: 1/4
