heat developed = 5*5*20*30 = 15000 joules
AnswerWith the information supplied, you can only determine the work done (W) by the circuit, not the heat (Q). To do so, you will need to know the mass (m) and specific heat capacity (C) of the conductor, and the temperature-difference between the conductor and its surroundings. The equation you need to do this is:
W - Q = m C (Tf-Ti)
With the information supplied, you can only calculate the work done: W = I2Rt.
Material with high resistance
Yes
resistance is the opposition to the flow of an electric current, therefore the current will decrease as the resistance increases. Resistance also creates heat. This is how the light globes in a circuit light up.
the formula for electric current is VI ,where v is voltage then I is the current. the unit used for current is ampere and volts for voltage. multiply the total I to the Voltage The formular of electric current is given by I=V/R ,I=P/V
silicon
V = I x R V = voltage, I = Current, R = Resistance or it can be calculate like this V = P / I V = Voltage, P = Electric Power, I = Current
V = I x R V = voltage, I = Current, R = Resistance or it can be calculate like this V = P / I V = Voltage, P = Electric Power, I = Current
An electric current follows the path of least resistance.
An electric furnace in which the heat is developed by the passage of current through a suitable internal resistance that may be the charge itself, a resistor embedded in the charge, or a resistor surrounding the charge.
40 A -providing the voltage remains constant.
resistance refers to the resistance of flow of electric current wile a capacitor is an electric device that stores energy.
electric current
no
It's resistance to electric current increases.
It increases resistance.
The path of least resistance.
