Volts=Current x ResistanceDrakkith said:What do V, I, and R in Ohm's law stand for? How are coulombs related to Ohm's law?
What's the definition of 'current'? How is it measured? What are its units?Precut said:Volts=Current x Resistance
To calculate the number of coulombs passing through a resistor, you will need to know the current flowing through the resistor, as well as the amount of time that the current is flowing. You can then use the formula Q=It, where Q is the charge in coulombs, I is the current in amperes, and t is the time in seconds.
Coulombs are measured in the International System of Units (SI) as the unit of electric charge. One coulomb is equal to the charge carried by a current of one ampere in one second.
Yes, the number of coulombs passing through a resistor can change over time. This can happen if the current or the time changes. In a circuit with a constant current, the number of coulombs passing through a resistor will increase as time passes.
No, the number of coulombs passing through a resistor cannot be negative. Coulombs represent the amount of positive charge passing through a point in a circuit, so it is always a positive value.
The number of coulombs passing through a resistor affects the overall circuit by determining the amount of charge that is transferred throughout the circuit. This can impact the voltage and current in the circuit, which in turn affects the performance of the circuit.
