How much power is consumed by a load drawing 5a with 120v across it?

real P= V * I *cos(phase angle between V and I)
for purely resistive loads or DC voltages this equals real power P=V*I = 120*5= 600Watts
for not pure resistive loads you'd have to measure the phase angle between Voltage and Current to get real power.
However, at home, the utility company charges for Complex power = V*I.
So you'd still pay for V*I.

The power consumed by the load can be calculated using the formula P = V * I, where P is power, V is voltage, and I is current. In this case, the power consumed would be 600 watts (120V * 5A).

How much power does a load drawing 15A with 120V across it consume?
The power consumed by the load can be calculated using the formula P = V * I, where P is power, V is voltage, and I is current. In this case, P = 120V * 15A = 1800 watts or 1.8 kilowatts.
For 1KW electricity does 240V or 120V cost less?
The cost of electricity depends on the rate charged by your utility company, not the voltage. The amount of power consumed (in kilowatts) determines the cost, regardless of whether it's at 240V or 120V. The rate charged per kilowatt-hour will determine the cost.
120v how much current does a 1500w resistace heater draw?
Using the formula Power = Voltage x Current, we can calculate the current: Current = Power / Voltage. Plugging in the values, we get 1500W / 120V = 12.5A. So, a 1500W resistance heater would draw 12.5A of current at 120V.
Where can you find a 120V electric power cable?
One can find a 120V electric power cable in stores such as Lowe's or Home Depot. It can also be purchased online through the store websites or through sites like rakuten for a cheaper price.
Can you run your neon sign of 120v 50hz 60hz 0.6a 7.5kv 30mA in an Australian 240v power outlet?
No, you cannot directly run a neon sign designed for 120V power on a 240V power outlet in Australia. The different voltage and frequency could damage the sign or be a safety hazard. You would need a voltage converter or transformer to safely operate the neon sign on the higher voltage.

How much power will a 230v adapter pull from a 120v outlet?
Power is multiplication of voltage and current. You need to know the load current drawing to establish the power. It is a bad idea to use 230 v adapter in 120 volts outlet

Where can you find a 120V power cable?
You can find a 120V power cable at your local hardware store. Look in the section under extension cords.
What is voltage across a 75 ohm resistor with 1.6 A current?
120v
Is 150 a lot of power?
I'll assume you mean 150 Watts in which case it isn't that much power. It would depend on the circuit from which you are drawing this power to ultimately determine if it is "a lot of power". A typical house in the US has 120V circuits with 15-20A breakers which would allow the circuit to handle a load of 1,800-2,400 Watts.
Can I use 120v 10a 1250 w cable for projector 110-240v power in India?
You can use 120v 10a 125w cable projectors 110-240v power in India.
