can any1 clue me into how u calculate the current through a resistor and the power absorbed by a resistor please!?
Current is the flow of electric charge, measured in amperes (A). It is typically measured using an ammeter, which is placed in series with the resistor in the circuit.
In a circuit with a resistor, the current will decrease as the resistance increases. This relationship is described by Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R): I = V/R.
Yes, current can flow through a resistor in both directions. In an alternating current (AC) circuit, the direction of current changes periodically, causing it to flow in both directions through the resistor.
According to Ohm's Law, as the voltage increases across a resistor, the current will also increase. This relationship is linear, meaning that the current will change proportionally to the change in voltage.
If the resistance of a resistor is increased, the current will decrease. This is because the relationship between current and resistance is inverse, meaning that as resistance increases, current decreases.
