I made this video to help explain the situation. Common electric circuits and combination of batteries in common electric circuits you can come across with batteries switches and connection wires.
Electrical Circuit With Two Bulbs And Two Batteries Stock
Circuits with multiple batteries. In a circuit involving one battery and a number of resistors in series andor parallel the resistors can generally be reduced to a single equivalent resistor. Exploration 189 analyzing a multi loop circuit solve for the current through each of the resistors in the circuit shown in figure 1822. Device which supplies energy to the circuit is called battery. We now examine the components of the simple circuit one by one. If you accidentally connect batteries of different voltages together your should run away especially if the batteries are large there is a real risk of explosion. In this case there will be an uncontrolled current flow as the high voltage battery discharges and the low voltage battery charges.
If all the batteries are part of one branch they can be combined into a single equivalent battery. With more than one battery the situation is trickier. We show it in the circuit as. In many circuits with more than one battery the batteries cannot be replaced by a single battery. R is the internal resistance of the. In such cases we rely on kirchoffs rules the loop rule and the junction rule.
