What voltage drop is there across 1kW electric heater, whose resistance when hot is `40Omega`?

Find the voltage drop across 18 Omega resistor in the given circuit.

How much current does an electric heater draw from a 220 V line, If the resistance of the heater (when hot) is 50 Omega ?

The voltmeter reads 40 V across 60 Omega resistance. The resistance of voltmeter is. .

Out of the two, a toaster of 1 kW and an electric heater of 2 kW , which has a greater resistance ?

In the above circuit, the voltage drop across the resistance (R) is

The rating of an electric heater is1100 w, 220V calculate the resistance when it operates at 220 v, also calculate the energy consumed in kwh in the month of November, if the heater is used daily for 4 hours at the rated voltage.

How much current will an electric heater coil draw from a 220 V source, if the resistance of the heater is 100Omega ?

An inductor coil is connected to an source through a 60Omega resistance in series. The source voltage, voltage across the coil and voltage across the resistance are found to be 33V, 27V and 12V respectively. The resistance of the coil is A. 30Omega B. 45Omega C. 105Omega D. 75Omega
