Electricity Electricity 1 / 10 A fuse works by Reducing the resistance of the circuit Breaking the circuit if the current is too big Reducing the current flowing Breaking the circuit if the resistance is too big 2 / 10 What kind of electricity does a lead acid battery stores ? AC(Alternating current) DC(Direct current) 3 / 10 The heating of a current carrying conductor is due to Repulsion between electrons and protons Attraction between electrons Loss of kinetic energy by protons Loss of kinetic energy by electrons 4 / 10 The unit of potential difference is Joule Faraday Volt Ohm 5 / 10 Which among the following is a better conductor of electricity? Iron Silver Aluminium Copper 6 / 10 Consider 2 bulbs A and B with the same power of 150 W from the same manufacturer. Bulb A is used for 2 hours while bulb B is used for 6 hours. Which bulb will glow more brightly? Which bulb will consume more energy? Bulb B Bulb A 7 / 10 An Electric heater consumes power at the rate of 2000 W and is used for 1 hour 30 minutes. What is the consumed energy? 2000 Kwh 3 Kwh 2 Kwh 3000 Kwh 8 / 10 The energy of 200Wh is consumed in 180 minutes. What is consumed power? 8/9 W 10/9 W 100/3 W 200/3 W 9 / 10 The resistance is measured in Watt Volt Ohm Ampere 10 / 10 Choose the correct expression for electric power. Power(Watt)=Voltage (Volt) * Current(Ampere) Power(Ampere)=Voltage (Volt) * Current(Watt) Current(Ampere)=Voltage (Volt) * Power(Watt) Current(Watt)=Voltage (Volt) * Power(Ampere) Your score isThe average score is 0% LinkedIn Facebook Twitter VKontakte 0% Restart quiz By WordPress Quiz plugin
