A 10-Ohm, 5-Ohm, and 3-Ohm resistor are connected in series to a 12 V battery. What is the total current in this circuit? 2 resistors of 3 Ω and 6 Ω respectively are connected in parallel across a 6 V battery. What is the current flow thro...
How does the size of a resistor affect its resistance?Suppose you're trying to force water through a pipe. Different sorts of pipes will be more or less obliging, so a fatter pipe will resist the water less than a thinner one and a shorter pipe will offer less resistance than a longer...
A shunt resistor (or shunt) is defined as a device that creates a low resistance path to force most of theelectric currentthrough the circuit to flow through this path. In most cases, a shunt resistor is made up of a material having a low-temperature coefficient of resistance, giving it ...

lever can be used to displace heavy objects. In an electronic circuit, transistors behave the same way i.e. a small current when applied to one of its three terminals ( the base ) a relatively huge current is allowed to flow through the remaining two leads ( from Collector to Emitter )...
The capacitor will start to discharge through the inductor. As it does, the inductor will create an electromagnetic field. Once the capacitor discharges, the inductor will try to keep the current in the circuit moving, so it will charge up the other plate of the capacitor. Once the inductor...
The way more reliable way is to measure the voltage that appears if the current flows through a (preferrably known) resistor. You can measure this votage (or the voltage difference between beginning and end of the resistor) with an MSPs ADC. ...
A large battery supplied current through a resistor to each wire pair (in the same way you saw in the previous section). When someone picked up the handset on his or her telephone, the hook switch would complete the circuit and let current flow through wires between the house and the ...
Calculating current & resistance In a series circuit, adding a resistor increases the resistance for the entire circuit. In a parallel circuit, adding a resistor provides another independent path for current to flow. As a result, more current flows for the same resistance. Because of ...
Hall Effect sensors are based on the “Hall Effect”, named after Edwin Hall, where current flow through a semiconductor placed perpendicular to a magnetic field will generate a voltage potential across the semiconductor material. For the purposes of current measurement, Hall Effect circuitry is plac...
