El-Shorouk Academy Acad. Year : 2023 / 2024 Higher Institute for Computer & Term : First Information Technology Year : First Dr. Shaimaa Othman Department of CS BS 131-Electronics Section two I. Problem solving :- 1- Indicate the resistance and tolerance for each resistor shown: Eng / Ammar Eid Eng / Alaa Hassan Eng / Nadden Ayman 2- In the circuit shown, the 10A fuse F1 blows when the value of R1 is: A) Greater than 1.2 Ohms B) Greater than 2.4 Ohms C) Less than 24 Ohms D) less than 1.2 Ohms 3- How much is current I1 in the circuit shown when switch S1 is open A) 100 A B) infinite A (until a wire melts) C) 1 mA D) Zero A 4- How much is current I1 in the circuit shown when switch S1 is closed A) 100 A B) infinite A (until a wire melts) C) 1 mA D) Zero A 5- Reading from left to right, the colored bands on a resistor are yellow, violet, brown and gold. If the resistor measures 513 with an ohmmeter, it is A) well within tolerance. B) Out of tolerance. C) right on the money. D) Close enough to be considered within tolerance. 6- What, exactly, is a short circuit? What does it mean if a circuit becomes shorted? How does this differ from an open circuit? 7- In the circuit, find iR3. 8- A 90A current flows into 4 resistors in paarallel. The four resistors are 5Ω, 6Ω, 12Ω, 20Ω. Find the current in each resistor. 9 - Calculate Vout for each circuit below, show your calculation? Eng / Ammar Eid Eng / Alaa Hassan Eng / Nadden Ayman 10 - A 12V Battery is rated at 100A-hours. How long can it supply a current of 20A? ⃝ 10 Hours ⃝ 5 Hours ⃝ 2.5 Hours II. Practical part :- Apply parallel and series connection Components:- 1- Breadboard 2- Battery 3- 2 Led 4- 2 Resistors Eng / Ammar Eid Eng / Alaa Hassan Eng / Nadden Ayman
