#1). Thinner wire.
Either replace a wire with one composed of thinner material, or
stretch the existing wire slightly so that it becomes thinner.
#2). Longer wire of the same thickness.

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 causes an alternating current in a generator?
The spinning magnet in generators.
What is the angle between no load current and the applied voltage in an ideal transformer?
A: Transformer by itself goes not alter the phases the output can be in phase or out of phase depending how you look at it.
What are the losses of a transformer?
Various energy losses occur in transformers:Copper losses, the resistance to the current flow in the windings which heats the conductors.Iron losses, which are of two kinds:eddy current losses which flow in the laminations of the core caused by the magnetization and re-magnetisation of the core, which also causes heatingof the core. Eddy current losses can be greatly reduced by not making the out of a solid piece of iron. That is why transformer cores are generally made of lots of separate thin "laminations" which are insulated from one another by being bonded together using an epoxy resin adhesive.hysteresis losses which are again caused by the magnetizing and de-magnetising of the core. These are reduced by making the laminations of silicon steels, which have lower hysteresis losses than plain iron.Together all these losses lead to a total efficiency of about 97 to 98%, which will alter depending upon the load current that the transformer is supplying.
Is alter bridge a christian group?
No, Alter Bridge Is A Alternative/Metal Band. Alter Bridge Is Made Up Of Members From Creed And The Mayfield Four So If You Have Ever Heard Those Bands You Know That Alter Bridge Is Not A Christian Band. They Are Just A Bit Soft.

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.

What is the input resistance of an ideal current-measuring DMM?
First of all, DMM stands for Digital Multimeter. The -multi implies the meter measures several different parameters, usually voltage, current, resistance, and sometimes other things such as frequency. The input characteristics of a DMM will be very different depending on the parameter selected. For current, the ideal meter would have zero input resistance. Since the ammeter is inserted in series with the circuit under test, any resistance will alter the measured current, introducing error in the measurement.
Which one of the following does not affect resistance of a wire 1 length 2 dielectric contstant 3 temperature 4 cross-sectional area?
Answer - None of the above.1. Resistance increases in direct proportion to an increase in length.2. Dielectric constant is the tricky one as the answer may depend on your application. Dieletric constants are usually associated with insulators, not conductors.For fixed voltage/direct current, as long as the dielectric's voltage specifications aren't exceeded, the insulator remains intact. Going beyond that voltage results in current flow (short) and a significant reduction in resistance. So in essence, changing the dielectric constant will alter the resistive properties of your conductor/nonconductor.For situations dealing with alternating currents, capacitance becomes an issue - as there is a current flow as the electric field fluctuates, but just as before - the dielectric constant is not a factor in a component's resistance... until its voltage ratings are exceeded.3. An increase in temperature usually results in a decrease in resistance.4. An increase in cross sectional area results in a decrease in resistance.Note: If "none of the above" is not an option here, then I would have to select #2 as being the answer, with some qualification as noted.
What are three synonyms for increase?
Change, alter, modify.
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.

NO!
Why won't a skydiver's speed continue to increase until his or her parachute opens?
Once a skydiver jumps off the plane, they will begin picking up speed. However, as the speed of the skydiver increases, the amount of air resistance acting upon them will also increase. The skydiver will continue to accelerate while his or her weight is greater than the air resistance. When the force of the air resistance becomes equal to the weight of the skydiver, the skydiver will stop accelerating and will continue falling at a constant speed, this is known as the terminal velocity. While travelling at terminal velocity, the skydiver will be able to adjust his or her body position in a way that will increase or decrease the air resistance and allow the diver to alter their speed. Releasing his or her parachute will drastically increase the amount of air resistance and therefore slow their descent significantly.
