What else can I help you with?
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
What generator produce voltage or power?
First of all power = voltage* current*power factor (a constant that varies on the characteristics of the electrical system) so to generate power a generator has to a level of voltage and should be capable to handle the current demand of the load (viz electrical load like the bulb we use at home or the pump motor - everything connected to the generator by electrical wire put together).
Why does a ac voltage applied across a load resistance produce alternating current in the circuit?
Because V = I x R or Voltage = Current x Resistance. Since resistance is linear there is a linear relationship between Current and voltage. If you have DC voltage you have DC current and if you have AC Voltage you have AC current. Note that there is a linguistic recognition of this relationship in that the voltage is described in terms of the current.
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 can power be calculated from current and voltage?
Power is the product of voltage and current -in other words, mutliply the two together.
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 power in parallel circuit?
Voltage will be same in all branches. Voltage= Current * Total Resistance
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 will a dc motor produce v but not an ac motor?
Motors do not produce voltage, current, or power. They use them.they produce mechanical output.
What generator produce voltage or power?
First of all power = voltage* current*power factor (a constant that varies on the characteristics of the electrical system) so to generate power a generator has to a level of voltage and should be capable to handle the current demand of the load (viz electrical load like the bulb we use at home or the pump motor - everything connected to the generator by electrical wire put together).
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.
