An ac series circuit has an impedance of 192 ω, and the phase angle between the current and the voltage of the generator is ϕ = −75°. the circuit contains a resistor and either a capacitor or an inductor. find the resistance r and the capacitive reactance xc or the inductive reactance xl, whichever is appropriate.

Resistance = 49.69 ohm

Capacitive reactance / inductive reactance = 185.45 ohm

Explanation:

We have given impedance of the circuit = 192 ohm

Angle between voltage and current

Power factor

We know that power factor is given by

Impedance is given by

Squaring both side

because growing process had stoped after 4-5 year

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
