What is the relationship between the load voltage and the load current?
Voltage, Current and Resistance Summary The relationship between Voltage, Current and Resistance forms the basis of Ohm’s law. In a linear circuit of fixed resistance, if we increase the voltage, the current goes up, and similarly, if we decrease the voltage, the current goes down.
Is load and current the same?
Load current in this context is simply the current thru the wire. As you say, a load consumes power. That power is delivered electrically, which means it is the product of voltage and current. The load current is just that current.
How are the voltage and current related?
The relationship between voltage, current, and resistance is described by Ohm’s law. This equation, i = v/r, tells us that the current, i, flowing through a circuit is directly proportional to the voltage, v, and inversely proportional to the resistance, r.
What is the relationship between the voltage and current for a resistive load connected to an AC supply?
In a resistive circuit Ohm’s Law states that: voltage is equal to current times resistance. For example, a current of 2 amps flowing through a resistance of 3 ohms is said to produce a voltage “across” that resistance of 6 volts.
What is mean by no load voltage?
The no load voltage is the terminal voltage when zero current is drawn from the supply, that is, the open circuit terminal voltage. Some portion of voltage drops down due to internal resistance of voltage source.
What is the meaning of load current?
The Load Current can be defined as 1) Full load current: the maximum current that an electrical machine can operate; 2) Rated Current: the current rated on the nameplate of an electrical machine; 3) Nominal Current: is generally mentioned in the specification documents that is normally the same value as the rated one; …
Does a load consume current?
In other words, the electrical load is a device that consumes electrical energy in the form of the current and transforms it into other forms like heat, light, work, etc. The electrical load may be resistive, inductive, capacitive or some combination between them.
When a resistive load is connected to an AC supply?
The change in direction of current in AC supply does not affect resistors behavior. So the current in the resistor will rise and fall according to the voltage as it rises and falls. The voltage and current in AC resistive circuit reach maximum, then fall to zero and reach minimum at the same time.
