The potential difference of 260 V is applied at the domestic circuit. An LED is connected to the circuit. An electric current of 0.35 A flows through the LED. Then
(i) Power of LED
(ii) Units consumed if the bulb is operating for 10 hr.

A potential difference of 250V is applied across a resistance of 1000 ohm is an electric iron.Find(i) th current and (ii) heat energy produced in 12 sec.

An electric tungsten bulb is connected into a home circuit. The home electric supply runs at 220 V potential difference. When switched on, a current of 0.45 A flows through the bulb What must be power (wattage)of the bulb? if it is kept on for 10 hours, how many units of electricity will be consumed?

If 90 W bulb is connected to a circuit with potential difference of 360 V,find the current flowing through the bulb?

Resistance of a bulb is 500 Omega . It is connected to a battery of potential difference 220 V. How much current will flow through it?

Choose the correct alternative and write it along with its allotted alphabet: If 220 V potential difference is applied across an electric bulb, a current of 0.45 A flows in the bulb. What must be the power of the bulb ?.

A current of 0.24 A flows through a conductor when a potential difference of 24 V is applied between its two ends. What is its resistance?

Read the given passage and answer the following questions: The home electrical connection consists of 'live','neutral' and 'earth wires. The 'live' and the 'neutral' wires have potential difference of 220 v. The earth ire is connected to ground. Due to a fault in the equipment or if the plastic coating on the 'live ' and the neutral wires gives away the two wires come in contact with each other and a large current flows through it producing heat . If any inflammable material (such as wood , cloth , plastic etc). exists around that place it can catch fire. Therefore a fuse wire is used as a precautionary measures. What is short circuit?
