Draw a copy of the circuit diagram in your lab book. Use arrows to show the direction in which the current flows through the circuit. Label the input circuit and the output circuit of the ...

In this circuit, a PNP transistor sources current. The base voltage is about 0.7 V less than the emitter voltage. So with 10.3 V on the base, the emitter has about 11 V and R1 sees about 1 V ...

Resistance in series If resistors are connected in series, the current must flow through both of them meaning the resistances are added together: R t o t a l = R 1 + R 2 This is when: resistance ...

Understand inrush current and its impact on power electronics design. Learn to manage surges that can exceed normal levels.

Aseries circuitconsists of two or more loads wired so that the current has to flow through each component (B).If any one component in a series circuit fails, the entire circuit fails as well (like ...

Different models, such as water flowing in a central heating system, can be used to understand electrical circuits. Find out more with BBC Bitesize. For students between the ages of 11 and 14.

Researchers at the Department of Energy's Oak Ridge National Laboratory are breaking technical barriers with faster circuit breakers to enable and protect the modern electric grid. The ORNL team ...

We talk about electrical current — just like current in a stream. Many introductory books on electricity try to relate voltage to water pressure, electric current to water flow, and resistance ...

In contrast to alternating current, or AC, which, depending on the supply's frequency, switches direction 50 or 60 times per second, the current in DC circuits flows only in one direction.
