Question: The current is directly proportional to the applied voltage and inversely proportional to the resistance, provided the temperature remains constant. what does this statement represent?
The statement "the current is directly proportional to the applied voltage and inversely proportional to the resistance, provided the temperature remains constant" represents Ohm's law. It is a fundamental law in electrical engineering that describes the relationship between current, voltage, and resistance in a circuit.
- Current is the flow of electric charge through a conductor. It is measured in amperes (A).
- Voltage is the difference in electrical potential energy between two points in a circuit. It is measured in volts (V).
- Resistance is the opposition to the flow of current in a conductor. It is measured in ohms (Ω).
According to Ohm's law, the current in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance. This means that if the voltage is doubled, the current will also double. And if the resistance is doubled, the current will be halved.
The temperature of the conductor must remain constant for Ohm's law to apply. This is because the resistance of a conductor typically increases with temperature.
Ohm's law is a very important law in electrical engineering. It is used to design and analyze electrical circuits. It is also used to measure the resistance of conductors.
Here is a mathematical formula of Ohm's law:
I = V / R
where:
- I is the current (in amperes)
- V is the voltage (in volts)
- R is the resistance (in ohms)
