Calculate the power consumed by a $10$ kW electrical heater operating at $240$ V$.$A DC motor operates at $500$ V and draws a current of $20$ A$.$ Calculate the power developed by the motor and the efficiency of the motor if its output power is $7\mathrm{.}5$ kW$.$A three$-$phase induction motor operates at $400$ V with an efficiency of $90\%.$ If the motor delivers $50$ hp of mechanical power, calculate the input power and the current drawn by the motor.Calculate the resistance of a copper wire of length $50$ meters and cross$-$sectional area $2$ mm$^2.$ Given the resistivity of copper as $1\mathrm{.}68$ x $10^-8$m$,$ determine the resistance of the wire.An electric circuit consists of a resistor, capacitor, and inductor in series with a voltage source of $100$ V and a frequency of $50$ Hz$.$ Calculate the impedance of the circuit and the phase angle between the current and voltage. What is abstraction in programming?
