We need to identify the term for the current assumed to flow in a circuit from the positive terminal to the negative terminal.
1. Understanding Electric Current:
Electric current is the flow of electric charge in a circuit. Historically, before the discovery of electrons, it was assumed that positive charges moved from the positive terminal to the negative terminal of a power source (like a battery).
2. Defining the Term:
This assumed direction of current flow, from the positive terminal to the negative terminal, is known as conventional current. In reality, electrons (which are negatively charged) move in the opposite direction, but circuit analysis uses the conventional current direction for consistency.
Final Answer:
The current assumed to be flowing in a circuit from the positive terminal to the negative is called conventional current.
Current electricity is defined as the flow of electrons from one section of the circuit to another.
There are two types of current electricity as follows:
The current electricity whose direction remains the same is known as direct current. Direct current is defined by the constant flow of electrons from a region of high electron density to a region of low electron density. DC is used in many household appliances and applications that involve a battery.
The current electricity that is bidirectional and keeps changing the direction of the charge flow is known as alternating current. The bi-directionality is caused by a sinusoidally varying current and voltage that reverses directions, creating a periodic back-and-forth motion for the current. The electrical outlets at our homes and industries are supplied with alternating current.
