What happens to the total circuit resistance when more devices are added to a series circuit?
resistance in series circuits increases as you add resistance.
In a series circuit, the total resistance increases as more devices, such as resistors or other components, are added. This is because in a series circuit, the current flowing through each device is the same, and the total resistance is calculated by adding up the individual resistances.
To understand why this happens, we can use Ohm's Law, which states that the current flowing through a circuit is equal to the voltage applied divided by the total resistance. In a series circuit, the voltage is divided among the various devices, and the total resistance restricts the flow of current.
When more devices are added in series, the individual resistances add up, resulting in a higher total resistance. This increased resistance hinders the flow of current through the circuit. As a result, the total circuit resistance increases.
To calculate the total resistance in a series circuit, you simply add up the resistances of all the devices. For example, if you have three devices with resistances of 10 ohms, 15 ohms, and 20 ohms connected in series, the total resistance would be 10 ohms + 15 ohms + 20 ohms = 45 ohms.
