Parallel Circuit With Variable Resistor. No matter how large the second resistor is the total current flowing from the power supply will be at least slightly higher than the current through the single resistor. Then parallel circuits are classed as current dividers.
A parallel resistor circuit is an electronic circuit in which all the resistors are connected side by side in different paths so that the same current will not flows through each resistor. Voltages only add algebraically for components in series. V total v parallel v known v total v parallel v known.
Circuit with a 6 v battery two 10 ohm resistors and a 20 ohm resistor in parallel.
Building simple circuits on terminal strips is one way to develop the spatial reasoning skill of stretching wires to make the same connection paths. Voltages only add algebraically for components in series. Consider the case of a single battery three resistor parallel circuit constructed on a terminal strip. If you add another resistor in parallel with the first one you have essentially opened up a new channel through which more current can flow.
