Power

In summary, the formula for calculating power is P = IV, where P is power in watts, I is current in amps, and V is voltage in volts. If power and voltage are known, you can find the current by dividing power by voltage, as in I = P/V. The unit of measurement for power is watts (W). No, power cannot be determined if only the current is given. Both voltage and current are needed to calculate power. To convert amps to watts, you can use the formula P = VI, where P is power in watts, V is voltage in volts, and I is current in amps. If voltage is known, simply multiply it by the current to get the power in watts.

What is the relationship between ##I_1## and ##I_x##? Are they really identical? How does this affect your constraint equation for the controlled source?

1. What is the formula for calculating power?

The formula for calculating power is P = IV, where P is power in watts, I is current in amps, and V is voltage in volts.

2. How do you find the current if power and voltage are known?

If power and voltage are known, you can find the current by dividing power by voltage, as in I = P/V.

3. What is the unit of measurement for power?

The unit of measurement for power is watts (W).

4. Can you determine the power if only the current is given?

No, power cannot be determined if only the current is given. Both voltage and current are needed to calculate power.

5. How do you convert amps to watts?

To convert amps to watts, you can use the formula P = VI, where P is power in watts, V is voltage in volts, and I is current in amps. If voltage is known, simply multiply it by the current to get the power in watts.
