In the following figure, the equivalent resistance between the points $A$ and $B$ in ohm will be :

On a bulb is written 220 Volt and 60 watt. Find out the resistance of the bulb and the value of the current flowing through it. 

In the circuit shown in figure, the current flowing through $5 \, \Omega$ resistance is 

An electric iron draws a current of 15 A from a 220 V supply, What is the cost of using iron for 30 min everyday for 15 days if the cost of unit (1 unit =1 kWhr) is 2 rupees ? 

What is the power produced by an appliance marked " $240 V$, $2 A"?$

In a metallic conductor, electric current is thought to be due to the movement of:

A $24 \ V$ potential difference is applied across a parallel combination of four $6 \ \Omega$ resistor. The current in each resistor is:

Electric current is to be passed from one body to another. For this purpose the two bodies must be joined by

An electric bulb works on $230\ V$ line and draws $0.1\ A$ current. The resistance of the filament is:

Four identical wires each having resistance $R$ are connected as shown in the figure. Equivalent resistance between A and B is:
