Do additional resistors affect power?
Of course. Additional resistors change total resistance, which changes current, which affects power.
How do resistors affect a circuit?
It reduces the current. As the current travels through the resitors it has some current that is left in the resistor. And
What factors affect current strength in a series circuit?
The number of resistors and their value. The wire and the junction points have resistance also.
Explain how the tolerance of various resistors affect the reliability of a digital circuit?
Hahn.
What is a resistors in circuit?
Resistors can be used to obtain desired voltages in other parts of the circuit. Or they can be used in conjunction with inductors and capacitors to affect a desired dissipation time (of voltage or current). A resistor may be made out of carbon or some other semiconducting material, or sometimes very long strands of conductor (silver for example) can be wrapped up to get very precise and consistent resistance values.
What would be the affect on the overall current in a parallel circuit if additional resistance was added in parallel?
Suppose we have a circuit containing a 15 volt battery and two 10 ohm resistors, and those resistors are in parallel. The total resistance of the two 10 ohm resistors = 5 ohms (1/10 + 1/10 = 1/5). Therefore the total amount of current flowing from the battery = 15/5 = 3 amperes. Adding a third 10 ohm resistor in parallel to the other two means that the total resistance of the circuit is now 3.333 ohms (1/10 + 1/10 + 1/10 = 1/3.333. Therefore the total current flowing from the battery = 15/3.33 = 4.5 amperes. Parallel resistances can be thought of as separate circuits. If we had a circuit containing a 15 V battery and a 10 ohm resistor, then 1.5 amperes would flow around that circuit (V = IR, 15 =10 x 1.5). If you keep adding 10 ohm resistors in parallel then the total current flowing out of the battery will step up accordingly: 1 resistor draws 1.5 amps, 2 draws 3 amps, 3 draws 4.5 amps, 4 draws 6 amps etc.
Can rusty crocodile clips affect a circuit?
Yes. If they sometimes make contact and sometimes don't, they behave just like ON/OFF switches. And if they make contact but rob some of the energy of the current that flows through them, then they behave just like resistors.
What is the affect of a series circuit on current?
by adding the the resistances in series the total resistance of the circuit increses and thus the crunt flowing in the circuit decrese. Ans 2 . the current in series circuit of constant resistance will always be the same . It will not effect the current .
Describe how a change in resistance would affect the current in a circuit?
As long as the voltage between the ends of the circuit remains constant, the current through the circuit is inversely proportional to the total effective resistance of the circuit.
How can an ammeter be connected in a circuit and not effect the flow of current?
The ammeter does affect the flow of current in a circuit, however, the resistance of the ammeter is so small in comparison to the circuit that the effect is negligible. It is connected in series.
How can a broken wire affect a series circuit differently than a parallel circuit?
In a series circuit, all the current passes through the one circuit. Any break will totally remove power from all of the circuit.Parallel circuits have more than one branch where the current can flow. A broken wire will only affect one part, the rest of the circuit will still pass current.In a series circuit, all the current passes through the one circuit.

If the resistance in the circuit is increased what will happen to the current and voltage?
* resistance increases voltage. Adding more resistance to a circuit will alter the circuit pathway(s) and that change will force a change in voltage, current or both. Adding resistance will affect circuit voltage and current differently depending on whether that resistance is added in series or parallel. (In the question asked, it was not specified.) For a series circuit with one or more resistors, adding resistance in series will reduce total current and will reduce the voltage drop across each existing resistor. (Less current through a resistor means less voltage drop across it.) Total voltage in the circuit will remain the same. (The rule being that the total applied voltage is said to be dropped or felt across the circuit as a whole.) And the sum of the voltage drops in a series circuit is equal to the applied voltage, of course. If resistance is added in parallel to a circuit with one existing circuit resistor, total current in the circuit will increase, and the voltage across the added resistor will be the same as it for the one existing resistor and will be equal to the applied voltage. (The rule being that if only one resistor is in a circuit, hooking another resistor in parallel will have no effect on the voltage drop across or current flow through that single original resistor.) Hooking another resistor across one resistor in a series circuit that has two or more existing resistors will result in an increase in total current in the circuit, an increase in the voltage drop across the other resistors in the circuit, and a decrease in the voltage drop across the resistor across which the newly added resistor has been connected. The newly added resistor will, of course, have the same voltage drop as the resistor across which it is connected.
