How much current does a 23 watt bulb consume?
To answer this question a voltage must be given.
How you know about the capacity of voltage regulator for your home?
The capacity of the regulator is measured in Watts (Power) and that is the voltage multiplied by the current.
What is a relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
What is the relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
What is my 240 v supply at home ac or dc?
The household supply in the UK is 240 V and is AC (alternate current).
What is term used when an Alternating current acts like a direct current?
Perhaps you are asking how the voltage of alternating current is measured, to be equivalent to the voltage of a direct current system. Alternating current and direct current have distinct properties. With direct current, voltage is at a constant polarity, and a direct current voltage source will maintain a uniform, constant voltage level. Alternating current reverses polarity at a given frequency and therefore it's voltage continuously varies from a positive peak voltage level, through zero, to a negative peak voltage level, repeating this cycle continuously. For this reason, voltage of an alternating current system, is measured in root-mean-square (rms), which is a voltage, which when multiplied by the current in amperes, calculates power which is equivalent to that of direct current of the same voltage and current values. With a typical sinusoidal waveform, the peak voltage of alternating current is divided by the square root of 2 to determine the rms voltage. The 120 volts output in the wall outlet in our home is actually about 170 peak volts.
Does the current in home wires oscillate due to oscillating ac voltage in homes?
Yes. In almost all cases, the current follows the voltage waveform. The peak amplitude of the current depends on the device or appliance that's drawing the current.
Can there be a current with no voltage?
No, There can't Be current without voltage
What is the relationship among voltage circuit and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
Why does my home AC charger charge my iPhone so much faster than my automobile DC charger?
Phone will charge faster with a larger charging current. Charging current depends on voltage, so your home charger likely has a higher voltage and therefore a higher charging current.
Why current leads in capaciter?
Capacitors resist a change in voltage. It takes current to effect a voltage change, resulting in the current "leading" the voltage. Similarly, inductors resist a change in current. It takes voltage to effect a current change, resulting in the current "lagging" the voltage.
How do you find the current if you have the resistance but not the voltage?
The current will be zero if there is no voltage.
