1. You have a difficulty in opening the metal lid of your jam jar. What will you choose: a) dip it in a cold water b) dip it in a hot water? Why? 2. Why the wire that is connected in the posts outside are are lightly saggy not tightly tied by the line man? 3. What do you think is the reason why there are always a small gaps in the road even in a tiled floor?

2. Task: Simple Wiring Connection Layout of your House a) Make a simple wiring connection layout of your own house like the image shown below. The layout will be according to your house and the equipment used in your house. Mention the total load and current drawn by each room/spaces and the recommended size of cables to be used beside the cable lines. The following image is just an example and it is not complete. You may use standard symbols of the equipment or draw with appropriate label, i.e. fan, light, switchboard, MCB ete. b) Add images of equipment used in your house with this question.

Short circuit is occurred when: Select one: a. The voltage between the two terminals is zero although there may be a nonzero current between the terminals. b. All of the given answers. c. There will be a zero-resistance connection between terminal A and B and therefore the 2 terminals are at the same voltage. d. A pair of terminals connected by a wire (of zero resistance).
1. The terms “open-circuit", “short circuit" and “dead short" are used in speaking electricity. Answer the following questions about these three terms: a. What is the value of the resistance of an open circuit? b. What is the value of the resistance of a short circuit? c. What is meant by a “dead short"? 5 DDPasalo-Electrical Engineering Department COE MMSU EE 121: Electrical Circuits I 2. When a switch is open, is the resistance between its terminals high or low? ¸Low 3. What is the resistance of a closed switch (ideally)? 4. Using each of the methods shown in (a) and (b) below, calculate the value of the equivalent resistance of a combination of R1 = 5 ohms and R2 = 20 ohms connected in parallel a. Using the equation: 1/Requivalent = 1/R, + 1/R2 + 1/R3 = b. Using the equation: Requivalent = (R, x R2) / (R, + R2) = Ω

The circuit diagram below is for a robot that walks around the room. It is designed to stop walking when certain conditions are met. a) In which of the following cases will the robot start walking? i. The robot is far from the wall. ii. The battery status is good. iii. The room lights are on. iv. Both i and ii. v. i, ii, and iii. vi. ii and iii, but not i. vii. i and iii, but not ii. b) Explain what happens to the robot if the light is turned off. ______________________________________________________________________________ ______________________________________________________________________________ c) If you remove the light sensor and the AND gate attached to it from the circuit from the circuit, which of the following are true and which are false? i. The robot will continue to walk with a low battery ii. The robot will stop walking if it is close to the wall iii. One of the remaining inputs (proximity sensor and battery status) is irrelevant to whether the robot walks or not.…
