* Ohms (Ω): Measure the resistance to electrical current flow. Higher ohms mean more resistance.
* Watts (W): Measure the rate at which energy is used or produced.
To calculate power (watts), you need to know the following:
1. Resistance (ohms): You have this (100 ohms)
2. Voltage (volts): The electrical potential difference across the resistance.
3. Current (amps): The amount of electrical current flowing through the resistance.
Here are the formulas:
* Power (P) = Voltage (V) x Current (I)
* Voltage (V) = Current (I) x Resistance (R)
Example:
If you have a 100 ohm resistor with 12 volts applied across it:
1. Calculate current: I = V/R = 12V / 100Ω = 0.12 Amps
2. Calculate power: P = V x I = 12V x 0.12A = 1.44 Watts
In conclusion: 100 ohms alone doesn't tell you how many watts it is. You need additional information about the voltage or current involved.
