1. Find the resistance of a conductor at 500 degrees Celsius given that its temperature coefficient at 200 degrees Celsius being 1/420 per °C and resistance at 420 °C being 200 ohms. 2. Two conductors, one of copper and the other of iron, are connected in parallel and carry equal currents at 25°c. How many percent of the total current will the copper conductor carry if the temperature is raised to 100°C? The temperature coefficients of resistance at 0 °C are 0.0043 /°C and 0.0063 /°C for copper and iron, respectively.

How was 0.1 found in the initial equation?

Would like to know the work behind the highlighted answers Q2: Consider a line of code- LDD $C100. Before execution of this line of code, the memory locations $C100, $c101, $C102, and $C103 was holding $33, $4A, $5A, and $6A, respectively. After execution of the code what would be the content of ACCA and ACCB: I $33 and $5A O $5A and 6A O $33 and $4A O $4A and 5A Q3: Consider a line of code- ADDD $C100. Before execution of this line of code the memory locations $C100, $C101, $C102, and $C103 was holding $33, $4A, $5A, and $6A, respectively and ACCA and ACCB were holding $00 and $11, respectively. After execution of the code what would be the content of ACCA and ACCB: O $33 and $5B O $33 and 5A $5A and $6A O $5A and $6B
