How is current in a circuit checked
Web11 feb. 2015 · With 29mA flowing in the Thevenin part of the circuit, you get a voltage on the top node of 23V - 200Ω·29mA = 17.2V. With the top node voltage of 17.2V you get a current downward in R2 of 13.2V/300Ω = 44mA. With 17.2V on the top node, you get a current in R1 of 29.2V/200Ω = 146mA. Current can be measured using an ammeter. Electric current can be directly measured with a galvanometer, but this method involves breaking the electrical circuit, which is sometimes inconvenient. Current can also be measured without breaking the circuit by detecting the magnetic field … Meer weergeven An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space.
