Answer:
it depends on temperature^^
Explanation:
hope this helped^^
The resistance of the sample is
Explanation:
The relationship between resistance of a material and temperature is given by the equation
where
is the resistance at the temperature
is the temperature coefficient of resistance
For the sample of nickel in this problem, we have:
when the temperature is
While the temperature coefficient of resistance of nickel is
Therefore, the resistance of the sample when its temperature is
is

Answer:
(a). Z = 54.54 ohm
(b). R = 36 ohm
(c). The circuit will be Capacitive.
Explanation:
Given data
I = 2.75 A
Voltage = 150 V
rad = 48.72°
(a). Impedance of the circuit is given by
Z = 54.54 ohm
(b). We know that resistance of the circuit is given by
Put the values of Z & in above formula we get
R = 36 ohm
(c). Since the phase angle is negative so the circuit will be Capacitive.
