Does current change in a series circuit?Ohm's Law:Ohm's law is named after its discoverer Georg Simon Ohm, a German physicist. It was discovered in the 1820's and relates the voltage V, current, I and resistance, R in a closed circuit. In equation form Ohm's law is: ...
Rearranging the equation: 10=Rlamp+5 Rlamp=10−5=5Ω Conclusion for Part (a): The resistance of the electric lamp is 5Ω. Part (b): Effect of connecting a 10 Ω resistor in parallel. 1. Understanding the Circuit: When a 10 Ω resistor is connected in parallel with the series comb...
We prove that in the case of one thin toroidal conductor, eddy current equations have as a limit Kirchhoff’s algebraic equation for circuits. This approximation is valid in the case of small resistivity and voltage.doi:10.1007/s00205-017-1136-xAmirat, Youcef...
Electric Current Equation Application Lesson Summary Frequently Asked Questions How do electric charges flow in a circuit? In a circuit, electric charge flows from areas of high concentration to low concentration. That is, the electrons, who are negatively charged and therefore repel each other, ...

The Q-factor of a parallel resonant circuit is the ratio of the current circulating in the parallel branches of the circuit to the supply current, that is, the current magnification. In a parallel circuit the Q-factor is a measure of current magnification, whereas in a series circuit it is...
Although the input resistance of the circuit in Figure 2.30 is ideally 0, there may be applications that require us to know a more accurate value for it. The following equation can be used to estimate the input resistance of the current amplifier in Figure 2.30: (2.47)RIN=R2(RX+RL)RX(1...
