Using the equation
I = P/V
, we can calculate how much current in amps would be required to get 100 watts out of this 6-volt bulb. You know that P = 100 W, and V = 6 V.
How do you calculate amps from voltage and current?
The formula is
(W)/(V) =(A)
. For example, if you have a power of 10W running at 5V, the current is 10W / 5V = 2A. This comes from the equation I = P / V.
What is the formula for amps?
A simple formula for calculating amps is
to take the watts and divide that by the volts
. So, for instance, if the wattage of the lighting fixture you’re working with is 60 and the volts are 12, divide 60 by 12 and you will get five, which are the amps.
How many amps is 220 volts?
13.64 Amps
, if you use 220 V.

How much current is used in homes?
Most homes have an electrical service of
between 100 to 200 amps
. Amperage is a measurement of the volume of electricity flowing through wires, and this measurement can vary between 30 amps in very old homes that have not been updated to as much as 400 amps in a very large home with extensive electric heating systems.
How many volts is 50 amps?
A 30 amp plug has three prongs – a 120 volt hot wire, a neutral wire and a ground wire – and is generally used on RVs with lower load requirements. A 50 amp plug has four prongs –
two 120 volt
hot wires, a neutral wire and a ground wire – that supply two separate 50 amp, 120 volt feeds.
Is volts more than Watts?
| Basis for Comparison Volts Watts | Definition It is the SI unit of potential difference and EMF. It is the SI unit of Power. | Formula |

What size breaker do I need for 2000 watts?
If your heater has a 2000 watt element, the amp draw can be easily calculated. 2000 / 120 = 16.667 amps. It appears at minimum, a
20 amp circuit
will be required.
How many volts is 1000 watts?
This can be either the hot wire or the neutral common wire in the circuit. Both of these wires will carry the current or amperage for the electrical circuit. Divide 1000 watts by 10 amperes and the resultant voltage would equal
100 volts
.
How many volts is 70 amps?

How many volts is 60 amps?
60-amp
240
-volt circuit: 60 amps x 240 volts = 14,400 watts.
How many volts is 30 amps?
A 30-amp outlet supplies 3,600 watts (30 amps multiplied by
120 volts
).
Which current is used in homes?
Many devices in your house need DC. When you plug things into the outlet in your house, you don’t get DC. Household outlets are
AC – Alternating Current
. This current has a frequency of 60 Hz and would look something like this (if you plotted current as a function of time).
Is your house AC or DC current?
When you plug things into the outlet in your house, you don’t get DC. Household outlets are
AC – Alternating Current
. This current has a frequency of 60 Hz and would look something like this (if you plotted current as a function of time).
