# Electricity and Electrostatics Questions **Part 1 - Multiple Choice Questions** 1. **Ohm:** - (a) energy - (b) electrical potential difference - (c) current - (d) resistance 2. **Volt:** - (a) energy - (b) electrical potential difference - (c) current - (d) resistance 3. **Ampere:** - (a) energy - (b) electrical potential difference - (c) current - (d) resistance 4. **Static Charges:** - (a) Neutrons - (b) Electrons - (c) Protons - (d) Positrons 5. **Basic Circuit Components:** - (a) Power source, load, wires - (b) Power source, switch, wires - (c) Power source, voltmeter, switch - (d) Wires, switch, load 6. **Lamp Connection:** - (a) Parallel - (b) Tandem - (c) Series - (d) Reverse order # Part 3 - Problem Solving **Table 1: Electrostatic Series** | Material | Charge Tendency | |---|---| | human skin | + (weaker tendency to gain electrons) | | rabbit fur | + | | acetate | + | | glass | + | | human hair | + | | nylon | +| | wool | +| | cat fur | + | | silk | +| | paper | +| | cotton | +| | wood| + | | amber | + | | rubber balloon | - (stronger tendency to gain electrons)| | vinyl | - | | polyester | - | | ebonite | - | 1. **Rabbit Fur and Hair:** If rabbit fur is rubbed on hair, electrons will move from the hair to the rabbit fur. The rabbit fur will become positive, and the hair will become negative. 2. **Wool and Balloon:** If wool is rubbed on a balloon, electrons will move from the wool to the balloon. The balloon will become negative, and the wool will become positive.
