Voltage Current Resistance Power Wheel

Voltage Current Resistance Power Wheel. Calculate power, current, voltage or resistance. The voltage v in volts (v) is equal to the power p in watts (w) divided by the current i in amps (a):

This is how the voltage (the potential) affects the current (the flow). The formula wheel of acoustics (audio) Wattage (w) = power = voltage 2 / resistance power = 12 2 / 2 = 12*12 / 2 = 72 watt.

This Is How The Voltage (The Potential) Affects The Current (The Flow).


If you need to deal with voltage, current, resistance or impedance, and power formulas, and you want to know what the differences are between what we call ac and dc formulas, you may find these ohms law power wheels useful. Keeping the resistance (the size of the pipe) the same, you can increase current by increasing the voltage. Voltage is the difference in charge between two points.

Voltage V = I × R = P / I = √ ( P × R) In Volts V Current I = V / R = P / V = √ ( P / R) In Amperes A.


The voltage v in volts (v) is equal to the current i in amps (a) times the resistance r in ohms (ω): The voltage v in volts (v) is equal to the square root of the power p in watts (w) times the resistance r in ohms (ω): E or v = voltage (volts) i= current (amps) r= resistance (ohms) so, if you need to find voltage, current, or resistance, simply place your finger over what you're trying to find and the formula wheel will do the rest.

Voltage [ v = i x r ] = 2 x 12ω = 24v power [ p = v x i ] = 24 x 2 = 48w Resistance r = v / i = p / i2 = v2 / p in ohms ω power p = v × i = r × i2 = v2 / r in watts w. From this definition of power, we can substitute the algebraic definitions above to produce a variety of other formulae, including ' power = current × voltage '.

I (Current) X R (Resistance) = E (Voltage)


Ohm's law states that ' voltage = current × resistance '. Voltage is the force which tries to force current flow. Similarly, if you increase the size of the pipe (decrease the resistance), without changing the height of the potential, you'll still get more flow.

P Is Power, Measured In Watts.


Power dissipated by a resistor the power dissipated by a resistor as heat, called joule heating, is given by p =∆vi =i2 r= ∆v 2. Power power (p) is a measure of the rate at which energy is delivered or used by a circuit element. To use the wheel, select the wanted quantity from the inner circle of the wheel and then the appropriate formula in that quadrant based on what you know about the electrical current you are working with.
