How can power be calculated from current and voltage?
Power is the product of voltage and current -in other words, mutliply the two together.
What is the formula for power delivered by a voltage source?
Power is voltage times current.
As the voltage applied to a circuit increases the current and the also increase?
answer is actually voltage
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.
What factors determine power?
Power = Current * Voltage * Power FactorAbove expression can further be explore as :1. For DC CircuitsPower = Current * Voltage2. For Single Phase AC CircuitPower = Current * Voltage * Power Factor3. For Three Phase AC CircuitPower = Line Current * Line Voltage * Power Factor
How much current does a 120v 1200w hair dryer draw?
Using the formula Power = Voltage x Current, you can rearrange to solve for current: Current = Power / Voltage. Plugging in the values, the hair dryer would draw 10 amps of current (1200W / 120V).
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 does ohms law apply to a hair dryer?
Ohm's Law can be applied to a hair dryer to determine the relationship between the voltage supply, current flowing through the device, and its resistance. By knowing the voltage of the power source and the resistance of the hair dryer (typically indicated on the device), you can calculate the current flowing through the hair dryer using the formula I = V/R, where I is the current, V is the voltage, and R is the resistance.
How can you calculate the current an appliance can use?
To calculate the current an appliance can use, divide the power rating of the appliance (in watts) by the voltage it operates on (in volts). The formula is: Current (in amperes) = Power (in watts) / Voltage (in volts). This calculation will give you the maximum current the appliance can draw under normal operating conditions.
What equation relates power to current and resistance?
Power = (current) times (voltage)Current = (Power) divided by (voltage)Voltage = (Power) divided by (current)
What is the relationship between voltage power and current?
The unit of power is watts, the unit of current is amps, and the unit of voltage it volts. Power = Voltage X Current Voltage = Power / Current Current = Power / Voltage In electricity, power is symbolized with a P, current with an I, and voltage with a V. The real formula looks like: P = V x I V = P / I I = P / V
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.
Does voltage divided by watts equal the current?
Electric power is not defined as current divided by voltage. Electric power (Watts) is equal to amps times voltage
What is the relationship between power, voltage, and current, and how can it be expressed mathematically using the formula power equals voltage multiplied by current?
The relationship between power, voltage, and current can be expressed mathematically using the formula: Power Voltage x Current. This formula shows that power is directly proportional to both voltage and current. In other words, an increase in either voltage or current will result in an increase in power.
What you get from mains voltage or current?
You get power, which is voltage * current (so both!).
A high voltage combined with a low current will deliver less power than a moderate voltage combined with a moderate current.?
Correct. Power is determined by the product of voltage and current (P = V x I). A high voltage with low current has less overall power output compared to a moderate voltage with a moderate current due to the relationship between voltage, current, and power.
HOW CAN you calculate power if you know the voltage and current?
P = I^2 R = IV = v^2 / R , Where P is power, I is current, R is resistance, and V is voltage. Given voltage and current, power = current * voltage, or P = IV.
