Can you calculate power by multiplying voltage and current?
Not enough information. Power = current x voltage. Since voltage can be anything, there is no way to calculate power. Time is irrelevant; though once you have the power, it can help you calculate energy (energy = power x time).
How do you calculate power loss from a resistor?
The power dissipated across a resistor, or any device for that matter, is watts, or voltage times current. If you don't know one of voltage or current, you can calculate it from Ohm's law: voltage equals resistance times current. So; if you know voltage and current, power is voltage times current; if you know voltage and resistance, watts is voltage squared divided by resistance; and if you know current and resistance, watts is current squared times resistance.
How many volts is 450 watts?
To calculate the voltage, you need to know the current (amperage) as well. The formula to calculate power (watts) given voltage (volts) and current (amps) is: Power (P) = Voltage (V) x Current (I). Without knowing the current, it is not possible to directly convert watts to volts.
How can calculate the power of contactor if you know the amper is 30 a?
To calculate the power of a contactor when you know the current (in this case, 30 amps), you can use the formula: Power (P) = Voltage (V) × Current (I). First, determine the voltage at which the contactor operates (e.g., 120V, 240V, or 480V). Then, multiply the voltage by the current: for example, at 240V, the power would be P = 240V × 30A = 7,200 watts (or 7.2 kW).
How do i fine an expression for power that involves only current and voltage?
You do not need ohm's law to relate power to current and voltage. Power is current times voltage. If you know current and voltage, you do not need to know resistance.
How much power used on 600v?
To calculate power used on a 600V circuit, you need to know the current flowing through it in amperes. Then, multiply the voltage by the current to find the power in watts using the formula: Power (W) = Voltage (V) x Current (A). Without the current value, we cannot determine the power consumption.
If you have only voltage and current?
If you know the voltage and current then you can solve for the power: P = V*I
How voltage is 350kv to watts?
To convert voltage to watts, you also need to know the current in the circuit. The formula to calculate power (watts) is: power = voltage x current. As voltage alone is given, you would also need the current flowing through the circuit to accurately determine the power in watts. Without the current value, it is not possible to convert voltage directly to watts.
How many watts are in 19.5 volts?
Impossible to know. You need to know both the voltage and current draw to calculate power (watts). Power in watts = Volts X Amps
What is the current in a 1000 watt microwave?
To calculate the current in a 1000 watt microwave, you would need to know the voltage it operates on. Using the formula Power = Voltage x Current, you can rearrange it to find Current = Power / Voltage. For example, if the microwave operates on 120 volts, the current would be approximately 8.33 amps (1000 watts / 120 volts = 8.33 amps).
How do you calculate current and voltage passing through light globes?
To calculate current passing through a light globe, you can use Ohm's Law: current (I) = voltage (V) / resistance (R). To calculate voltage across a light globe, you can rearrange Ohm's Law to solve for voltage: voltage (V) = current (I) * resistance (R). Just make sure you know the resistance of the light globe in ohms.
How many watts are in 0.1A?
To calculate the number of watts in 0.1A, you need to know the voltage of the circuit. The formula for power is P = V x I, where P is power in watts, V is voltage in volts, and I is current in amperes. Without knowing the voltage, it is not possible to determine the power in watts.
