2.1 The resistance of a length of wire at the beginning of an experiment is found to be 60 Q at an ambient
temperature of 1'C. Determine its resistance at a temperature of 93°C. Take the coil's temperature
coefficient as 0.24x10 at 0°C.
2.2 For the given circuit below, determine the current through the Ammeter.
Given data: R1: Blue-Gray-Black-Gold, R2: Orange-Orange-Brown-Silver
R3: Red-Red-Brown-Gold, R4: Gray-Red-Brown-Gold,
R5: Brown-Red-Brown-Gold, R6: Orange-Orange-Brown-Gold,
R7: Brown-Black-Brown-Gold, VDC1: 1000V
Assume all resistance values were found to be an exact match to their respective E12 values.
