What equation relates power to current and resistance?
Power = (current) times (voltage)Current = (Power) divided by (voltage)Voltage = (Power) divided by (current)
How does voltage and current work together to produce power?
That depends on the exact circumstances. For example, in electrical circuits, power = I2R. However, since the current, in turn, depends on the voltage and the resistance, it is better to express this as V2/R. For mechanical energy, power is basically speed times force.
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
Why is the formula squared in power dissipation of electrical resistance?
The fundamental equation for the power of any load is the product of the voltage across the load and the current through it: P = U I.Since voltage is the product of current and resistance (U = I R), we can substitute for voltage in the original equation:P = U I = (IR) I = I2R
Why During transmission of power it is transformed as high voltage rather than high current how is this possible as current and voltage are directly proportional?
Voltage and current are actually inversely proportional to one another. The formula P=IV is what you need to look at here, where P is Power, V is voltage, and I is current. Rearranging the equation you will see that V = P/I. You can see that if you increase voltage, while holding power constant, current is reduced. Now, to your question. The losses on a transmission line are proportional to the current flowing on the line, so transmitting at high voltage (and hence low current) is beneficial as it reduces the amount of power that is lost due to resistance in the line itself.
What equation relates power to current and resistance?
Power = (current) times (voltage)Current = (Power) divided by (voltage)Voltage = (Power) divided by (current)
How do you find the voltage?
Using Ohm's law, you can find voltage if power is given. The equation needed to solve for power is P(Power)= Voltage(E) x Current(I). Ohm's Law describes the relationship between resistance, current, power, and voltage.
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 equation for power in physics?
There are several equations that involve power. The basic definition of power is energy divide by time, so that is one equation. In electricity, if you have a DC current, power = current x voltage. In the case of AC, power = current x voltage x power factor (in many cases, the power factor is close to 1).

How many amps is in 750mA?
Amps are not directly convertible to horse power, which is a measure of power. Power is current times voltage. Therefore on a 240 v supply, 750 amps equals 180,000 watts. One horse power is 746 watts.
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.
If you multiply the voltage in a circuit by the current what are you going to get for your answer?
Voltage x current = power (watts)
What is an equation for power?
Power = (energy used)/(time to use it)Power dissipated by an electrical circuit =(voltage across the circuit) x (current through the circuit)or(resistance of the circuit) x (square of the current through the circuit)or(square of the voltage across the circuit)/(resistance of the circuit)
Relationship between current and resistance?
Ohm's law: voltage = resistance time current.
What you get from mains voltage or current?
You get power, which is voltage * current (so both!).
