How are resistors connected in a series circuit?
In a series circuit, the output current of the first resistor flows into the input of the second resistor; therefore, the current is the same in each resistor. In a parallel circuit, all of the resistor leads on one side of the resistors are connected together and all the leads on the other side are connected together.
How to calculate the power dissipated by a resistor?
(b) Find the current supplied by the source to the parallel circuit. (c) Calculate the currents in each resistor and show that these add together to equal the current output of the source. (d) Calculate the power dissipated by each resistor. (e) Find the power output of the source and show that it equals the total power dissipated by the resistors.
How are resistors related to the flow of charge?
Basically, a resistor limits the flow of charge in a circuit and is an ohmic device where Most circuits have more than one resistor. If several resistors are connected together and connected to a battery, the current supplied by the battery depends on the equivalent resistance of the circuit.
Is the sum of the potential drop of each resistor equal to zero?
For (Figure), the sum of the potential drop of each resistor and the voltage supplied by the voltage source should equal zero: Since the current through each component is the same, the equality can be simplified to an equivalent resistance, which is just the sum of the resistances of the individual resistors.
Why do you put a resistor on the positive side of the cable?
If a resistor is suppose to resist over current to the load through a cable in a series DC circuit then why would you ever place a resistor on the positive cable side instead of the negative cable side.
How is the power dissipated by a resistor found?
The power dissipated by each resistor can be found using , and the total power dissipated by the resistors is equal to the sum of the power dissipated by each resistor. The power supplied by the battery can be found using .
