Resistors don't care whether a d.c. or an a.c. current passes through them. So, yes, they can.

When an inductor and resistor are connected in parallel by how many degrees is the current flow through the resistor out of phase with the current flow through the inductor?

When a resistor and an inductor are both connected to an AC supply, the current in the resistor is in phase with the voltage, while the current in the inductor is a quarter-cycle (90 degrees) behind. Supposing they both draw 1 amp on a 12-volt AC supply. The resistor will dissipate 12 watts, while the inductor will dissipate no power. Any power that enters the inductor comes back to the generator in a later part of the cycle. But the current drawn from the supply is 1.414 amps, so this would be a load with a power factor of 0.707.


Do laptop work on ac or DC and how?

A laptop runs on DC. Either from the battery, or the external power supply, which converts AC power to DC.


Does tube light work with ac or dc?

Fluorescent lights work just fine on DC voltage, BUT one needs a current limited power source to stabilize the circuit against the negative resistance of the gas discharge. This can be done with either a resistor or an electronic circuit. The resistor solution is too lossy because excess voltage from the dc csupply has to be converted to heat across the resistor. Electronic switching supplies could supply a fluorescent light with a dc voltage and current without the losses. But that's technological overkill and most circuits still supply AC.


Can a bad ac resistor cause the ac not to work?

Yes, a faulty AC resistor can cause the air conditioning system not to work properly. The resistor controls the speed of the blower motor, and if it fails, the motor may not operate at all or may only work at one speed. This can lead to inadequate airflow and ineffective cooling. Therefore, addressing a bad AC resistor is essential for restoring proper function to the AC system.


How does DC to ac power supply work?

If having DC and AC is required then a PWM pulse width modulator is required to chop the DC to make AC


Ac power that is converted to heat in a resistor is known as?

real power (as opposed to imaginary power, which is not dissipated)

What happens when you connect 230V ac supply directly to a diode with the help of resistor of the order kilo ohms?

When you connect 230V ac supply directly to a diode with the help of resistor of the order kilo ohms, the diode will conduct on alternate half cycles. Forward bias current will be 230ma for 1KOhm, or 23ma for 10KOhm. Power across the resitor will be 25W for 1KOhm, or 2.5W for 10KOhm. Bottom line - the resistor will get very hot - and if not rated correctly, will be destroyed.


Where should ac or DC supply be used?

The type of power supply being used (AC or DC) should match the power requirements of the device it will be supplying power to.
