How do you calculate the power consumed by a resistor in series?

Power can also be calculated using either P = IV or P=V2R P = V 2 R , where V is the voltage drop across the resistor (not the full voltage of the source).

When two 6 ohm resistors are connected in parallel what will be the total resistance?

In the same manner, the presence of two 6-Ω resistors in parallel would be equivalent to having one 3-Ω resistor in the circuit.

How do you find the power of a series?

The total power in a series circuit is equal to the SUM of the power dissipated by the individual resistors. Total power (PT) is defined as: PT = P1 + P2 + P3… Pn. As an example: A series circuit is made up of three resistors with resistance values of 5 ohms, 10 ohms, and 15 ohms.

How do you calculate the total power consumed in a circuit?

Electrical energy is the product of power multiplied by the length of time it was consumed. So if we know how much power, in Watts is being consumed and the time, in seconds for which it is used, we can find the total energy used in watt-seconds. In other words, Energy = power x time and Power = voltage x current.

What is the effective resistance if 6 ohm and 3 ohm are connected in parallel?

Answer: Put 3 ohms in parallel with 6 ohms to produce an equivalent of 2 ohms by the parallel equivalent resistance rule [1/(1/3 + 1/6) = 2] Place that parallel combination in series with the other 2 ohms to get 4 ohms, since series resistances simply add [2+2=4].

What will be the equivalent resistance when 3 ohm and 6 ohm are connected in parallel combination?

Calculate the equivalent resistance when two resistances of 3 ohms and 6 ohms are connected in parallel. Thus, the equivalent resistance is 2 ohms.

How many watts is a 6 ohm speaker?

The speaker is 4-8 ohm. If the speaker was only 6 ohm then it would be 145 watts. If the speaker was only 8 ohm then it would be 109 watts. In most cases, the actual power dissipated by the speaker will be a fraction of one WATT at normal listening level.

What is the current draw of a circuit with a resistance of 6 ohms 120 volts is applied to the circuit?

What is the current draw of a circuit with a resistance of 6 Ohms when 120 Volts is applied to the circuit? 20 Amps: Follow the steps in the formula I=E/R (solve for I) : 120÷6=I(20 amps).

What is consumed in a circuit?

Electrical power is the “rate” at which energy is being consumed in a circuit and as such all electrical and electronic components and devices have a limit to the amount of electrical power that they can safely handle. For example, a 1/4 watt resistor or a 20 watt amplifier.
