WHAT IS A CHARGE?
▸ Before we can understand current, we need to understand
what a charge is
...
These can be either positive or negative
...
CURRENT
WHAT IS CURRENT?
▸ Current is the rate at which charge flows
...
▸ To calculate current we use the equation: Q=It, where
▸ Q is charge in Coulombs,
▸ I is Current in Ampere,
▸ and t is time in seconds
...
▸ It is measured in Volts, each Volt is equal to one Joule of energy
per Colombo of Charge
...
RESISTANCE
RESISTANCE
WHAT IS RESISTANCE?
▸ Resistance is the opposition of flow of current
...
▸ Resistance is calculated as: V=RI, where
▸ V is potential difference in Volts,
▸ R is Resistance in Ohms,
▸ and I is Current in Ampere
