In a parallel circuit a parallel branch is usually called which current or resistance or voltage path?

A parallel branch is a current path. In general, current follows paths, voltage drops across components, and resistance is the voltage divided by current of specific circuit elements.


Why can you ignore the resistances of wires in circuits with lower current?

Actually, it depends on the resistance of the other components in the circuit, and not so much on whether or not the total circuit current is low or not. Often, conductor resistance is ignored because it is so much lower than the active components that it does not matter. In a circuit with low resistance components, however, conductor resistance can be important, even if the total current is relatively low, because the voltage drop over the wire becomes a significant part of the overall circuit. To answer the specific question, even though its slightly misleading, conductor resistance does tend to become important in high current circuits because the voltage drop over the conductor (Ohm's Law: Voltage is current times resistance) can become high. Even in high current circuits, however, if the conductor is substantially less resistive than the components, the tendency is still to ignore it, except that you have to account for heating of the conductors along with heating of the components.


They say current is what kills people and not voltage but why then in electronics does high voltage burn your components but high current does not?

This is a 'chicken and egg' situation. The current passing through your body is determined by the voltage applied across your body, together with the resistance of the current path. So whilst it is true that it is the current that harms you, the voltage has to be high enough to cause the necessary amount of current to flow. In other words, it is equally valid to say that it is the voltage level that causes electrocution. An analogy might be, which kills you: the height through which you fall, or hitting the ground? Obviously, hitting the ground is what kills you, but the height from which you fall determines how hard you are going to hit the ground. As far as damage to electrical circuits is concerned, excessive voltage is responsible for insulation breakdown, while current is responsible for components to overheat. So high current will most certainly damage those components.


What components compose the excitation current of a transformer. How are they modeled in the transformer 's equivalent circuit?

The magnetization current can be broken-down into two components: the first is in phase with the supply voltage and is responsible for the losses, whereas the second component lags the supply voltage by 90 degrees and in responsible for the magnetic field.


Can there be a current with no voltage?

No, There can't Be current without voltage

What is the relationship between the current and the components in a purely capacitive circuit?

In a purely capacitive circuit, the current and the components have a relationship where the current leads the voltage by 90 degrees. This means that the current and voltage are out of phase in a purely capacitive circuit.


Where are resistors placed to control voltage and current?

A: A RESISTOR is a passive component it cannot control voltage these components and/or current it can however limit


What is the relationship between the current in an LC circuit and the voltage across its components?

In an LC circuit, the current and voltage are related by the equation V L(di/dt) Q/C, where V is the voltage across the components, L is the inductance, C is the capacitance, Q is the charge, and di/dt is the rate of change of current. The current in the circuit is directly proportional to the rate of change of voltage across the components.

What does the voltage current graph represent in an electrical circuit?

The voltage-current graph in an electrical circuit represents the relationship between voltage (V) and current (I) flowing through the circuit. It shows how the current changes with respect to the voltage, indicating the behavior and characteristics of the circuit components.

Why do different components draw different currents?

Different components draw different currents because they have varying resistance values. Ohm's Law states that current is directly proportional to voltage and inversely proportional to resistance. Therefore, components with higher resistance will draw less current, while components with lower resistance will draw more current for the same voltage.


In a series circuit what happens to the current if you increase the number of components in the circuit?

The current (amps) will remain constant, but the voltage will drop.


Difference between active and passive components?

ACTIVE COMPONENTS The components which produce the energy in the form of current or voltage are called as active components. Example:transistors etc,. PASSIVE COMPONENTS The components which stores the energy in the form of current or voltage are called as passive components. example:inductors,resistors,capacitors etc,.

What is Difference Between Current Source and Voltage Source?

A current source varies the output voltage to maintain the desired current. A voltage source has a constant output regardless of the current draw (up to the capacity of the supply, of course).
