What is the current?Which physical quantity is defined as the rate of flow of electric charge?What is the SI unit of electrical resistance?A potential difference of 12 V is applied across a resistor and a current of 3 A flows. What is its resistanceOhm's law gives the relationship between which set of quantities for a conductor at constant temperature?Three resistors of 2 ohm, 3 ohm and 5 ohm are joined in series. What is their effective resistance?Two resistors of 6 ohm and 3 ohm are connected in parallel. What is the effective resistance of the combinatioHow does the resistance of a metallic wire change when it is made thicker, keeping its length and material theAn electric bulb is rated 60 W at 220 V. What current does it draw when operating normally?What does the unit kilowatt hour (kWh) measure?An electric heater of power 1000 W is used for 3 hours every day. How much electrical energy does it consume iA torch bulb is rated 3 V and draws a current of 600 mA. What electric power does it consume?Why does a bulb glow when the switch in a simple circuit is closed?A wire of resistance 10 ohm is stretched uniformly until its length becomes three times the original. What is Two resistors give 2 ohm when joined in parallel and 9 ohm when joined in series. What are the two resistance An electric iron draws power at 420 W and 180 W at its two settings, on a 220 V supply. By how much does the cA wire of resistance R is cut into five equal parts. What is the resistance of each part?What is the role of the earth (ground) wire in a domestic electric circuit?
