Question
ot. Answer the following Car batteries are rated in ampere-hours (A h). To what physical quantity correspond (voltage, current, charge, energy, power.... 12 Mark) a do ampere-hours Your electric bill gives your consumption in units of kilowatt-hour (kW-h). Does this unit represent the amount of charge, current, voltage, power, or energy you buy? [2 Mark] b. Q2. Electric circuits are sometimes explained using a conceptual model of water In this conceptual model, the voltage source is represented as a pump that pumps water through pipes and the pipes connect components in the circuit. Is a conceptual model of water flow pipe an adequate representation molocules and pipes? How are they different? 12+2-4 Mark] of the circuit? How are electrons and wires similar to water Examination Paper Cover Sheet Page 4 of 13Explanation / Answer
1a) ampere hours indicates charge. It quantifies charge.
b)kilowatt hour indicates energy bought by us
2)yes. Conceptual model of water flowing through a pipe is adequate representation of an electric circuit. Electrons and water are similar to water molecules and pipes. in electric circuit, electrons flow through wires. Likewise, water flows through pipes in the netweork of pipes. Also, in electric circuit, electrons flow from high potential to low potential and in pipe flow, water flows from high energy state to low energy state.
