What are two ways to alter the wire to increase the resistance in the electric circuit?
The resistance can be changed in following two ways:
1.By change the length of the wire.
2.By changing the area of cross section of the wire.

What are 2 ways you could alter a wire to increase the resistance in an electric current?
#1). Thinner wire.Either replace a wire with one composed of thinner material, orstretch the existing wire slightly so that it becomes thinner.#2). Longer wire of the same thickness.
Why a voltage is always connected in parallel?
Because Voltmeter measures potential difference BETWEEN two points so it should be connected to these two points and the only way for circuit and voltmeter to be both connected to the same 2 points is in parallel. Ampermeters measure the current THROUGH some circuit so the same current that is flowing through this circuit should flow through the ampermeter too. The only way is to let the current going through the circuit to go through the ampermeter later or before, so you have to connect ampermeter in series with your circuit. The fact that voltmeters have high resistance while ampermeters have low resistance is the side effect of the way how they are connected to reduce the error introduced by devices into measured value.
Why is a contact screw fitted in an electric bell?
The screw adjusts the size of the gap between the spring attached to the armature and the circuit wiring. This gap has to be just the right size for the make-break action to work properly. Wear and tear and vibrations can alter the gap, or conceivably even large temperature differences, so an easy way to put it back is necessary.
Why is voltmeter connected in parallel and ammeter connected in series in a circuit?
An ideal voltmeter has infinite impedance(resistance). If you were to break the circuit and put it in series and try to make a measurement, it is easy to see that the circuit would act completely differently and your measurement would be wrong. An ideal ammeter is always connected in series because it has 0 resistance, so all of the current would flow through it, and not through the wire that you are trying to measure the current of.A better answer though is to think about what you are trying to measure. When you say something is 3 Volts, that is a difference between the voltages at two different points. If you want to see what the voltage drop across a resistor is, for example, you need to put one probe of the voltmeter on one side of the resistor and the other probe on the other side of the resistor. That setup is simply called being in parallel.Voltage is potential difference between two points, hence measured across or in parallel, where as current is measured in series since current flows (*)
Which ammeter DMM or VOM has the higher loading effect Why?
A digital multimeter (DMM) typically has a lower loading effect compared to a volt-ohm meter (VOM), particularly older analog models. The loading effect refers to the impact a measuring device has on the circuit being measured; a higher loading effect can alter the circuit's behavior. DMMs generally have higher input impedance, which minimizes the current drawn from the circuit, resulting in less loading. In contrast, VOMs, especially those with lower impedance, can significantly affect circuit performance when measuring current.
What are two ways you could alter the wire to increase the resistance in the electric curcuit?
You could increase the length of the wire or decrease its thickness to increase resistance in the electric circuit. Both of these changes will hinder the flow of electrons through the wire, resulting in higher resistance.

How do you solder the rails on model railways?
They generally require no soldering, but if you wish to (to increase the reliability of the electric circuit), you apply a small amount of solder on the fishplates between the rails. Be aware that you won't be able to alter the layout after doing this
What do you call a variable resistor that is set up to alter the size of the current in a circuit?
A thermister is a device that changes resistance depending on temperature. A photo resistor changes resistance based on light. Both of these could be used with an amplifying circuit to vary current flow.
Do bend in the wire effect the electric resistance?
Yes, bending the wire can potentially affect its electrical resistance. The resistance of a wire is influenced by its dimensions, material, and temperature. Bending a wire can alter its cross-sectional area, length, or even cause deformations that impact the flow of electrons and increase resistance.
How does changing the voltage in a circuit affect the current in the circuit?
Changing the voltage in a circuit will alter the current flowing through it. According to Ohm's Law, the current is directly proportional to the voltage in the circuit. Increasing the voltage will lead to an increase in current, and vice versa.
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.
Why an ideal voltimer must infinity resistor?
An ideal voltmeter must have infinite resistance to prevent it from drawing any current from the circuit it is measuring. If it had finite resistance, it would alter the voltage across the component being measured, leading to inaccurate readings. By having infinite resistance, the voltmeter ensures that it does not influence the circuit, allowing for precise voltage measurements.

What are the two factors of a wire that will alter its resistance?
The resistance of the wire is directly proportional to the length and inversely proportional to the area of cross section. Also it depends on the material of the wire with which it is made. So three factors. Length, area of cross section, material.
