Depends on the voltage. R equals V2/P . Or the current: R equals P/I2 .
To find the current in the circuit, you can use the formula: Power = Current^2 * Resistance. Given the values, you can rearrange the formula to solve for current: Current = sqrt(Power / Resistance). Plugging in the values, you get Current = sqrt(2 / 30) which simplifies to approximately 0.27 amperes.
The formula for calculating current in a circuit when given the values of power and resistance is i p/a.
No, power is not directly proportional to resistance. The power dissipated in a circuit is given by P = I^2 * R, where I is the current flowing through the circuit and R is the resistance. This means that power is proportional to the square of the current but linearly proportional to resistance.
The power in a circuit is determined by multiplying the square of the current flowing through the circuit by the resistance of the circuit. Without specific values for current and resistance provided, the precise power cannot be calculated.
The formula for calculating the power dissipated in a resistor, known as the i2r power, is P I2 R, where P is the power in watts, I is the current in amperes, and R is the resistance in ohms.

power=work done/time interval
All resistances will emit heat energy when a current flows. The heat production rate (or power) can be found by any of these formulas: Power = Current * Voltage Power = Current2 * Resistance Power = Voltage2 / Resistance. Power is given in Watts when Current is in Amps, Voltage in Volts, and Resistance in Ohms.
You must first solve for current or amperage, if you know only voltage and resistance. The symbol for current is normally "I" or "A". The formula is A=V / R . So divide the voltage by the resistance to obtain the current. Then the formula for wattage or power (P) is P= V x A . So then you would multiply the voltage by the current to obtain the power in watts.
Power is voltage squared, divided by resistance (P = V2/R) so, for a given voltage, the lower the resistance, the greater the power!
in this theorem we will neglect the given resistance and in next step mean as second step we will solve
power=i square*resistance or power=v suare/resistance

Okay. Resistance by ohms law is given by R = V/I But Power P = V * I Dividing R/P = 1/ I 2 Or R = P / I squared For a constant power, resistance is inversely proportional to I squared and not simply proportional to.
