In the unlikely event that you don’t know the wattage of an appliance, but you do know the voltage (almost always 230V) and the resistance (ohms), you can calculate the amperage of the device. Ohm’s lawstates: Current (I) = Voltage (V) / Resistance (ohms or Ω) Again, using a...
Thus, the currentIflowing through a conductor is equal to thevoltageVacross the conductor divided by theresistanceRof the conductor. How to Calculate Current From Power You can also calculate electric current in amps if you know the power drawn from the circuit using theWatt’s Law power formula...
Calculating Resistance from Current and Voltage Step 1 Write down all of the information that the problem gives you. Most simple physics problems that ask you to calculate resistance give you values for current and the voltage in the problem. Step 2 Convert all of the units in the problem to...

The Wheatstone bridge is an electrical bridge circuit used to measure resistance. The Wheatstone bridge network consists of four resistors Ra, Rb, Rc and Rx interconnected. If the ratio of the two resistances Rb / Ra is equal to the ratio of the two Rx / Rc, then the voltage across ...
In summary, the conversation discusses how to determine the voltage, current, and power in a circuit with 16 globes. The speaker calculates the voltage per globe to be 1.5V and the resistance per set of 8 globes to be 15 ohms. They then use the formulas V=IR and P=IV to...
