Describe two things you can do to increase the acceleration of an object?
Increase the force on the objectDecrease the resistance to motion (lubricate, remove resisting stuff like the air...)
What would be the effect of adding a load in parallel to a parallel circuit?
Ohm's Law says Voltage = Current x Resistance With constant voltage, an increase in resistance decreases the current. Now the load can be added in two basic ways. If the load is added in series the resistance will increase. If you add load in parallel the resistance will decrease and the current will increase from the source.
What are two ways to increase the current in a simple cell?
Two ways to increase the current would be to increase the surface area of the electrodes and make changes to the electrolyte to speed up the movement of the ions (this might involve increasing the concentration of the electolyte or warming it up to speed up diffusion).
What is the resistance if the current is 0?
If you measure zero current, then there are two possibilities,and there's no way you can tell which one is true withoutanother measurement.-- The voltage across the circuit may be zero,and the resistance could be anything.-- The resistance of the circuit may be infinite,and the voltage could be anything.
There are three sources of resistance in a parallel circuit two of them are rated at 20 ohms the other at 10 ohms what is the circuit's total resistances?
5 ohms.
Describe two ways to increase the current in a circuit?
1. Increase the voltage while holding the resistance constant.and2. Decreasing the resistance while holding the voltage constant.For a fixed load, increase the supply voltage. For a fixed supply voltage, increase the load.So that there is no confusion, 'increasing a load' means reducing the resistance (in the case of a d.c. circuit) or reducing the impedance (in the case of an a.c. circuit).
What are the two ways of decreasing current in a standard test circuit?
Increase the resistance (ohms) Decrease the voltage (Volts)
How do you connect a voltmeter in parallel circuit?
A voltmeter is used to measure potential difference across two points in an electrical circuit . The voltmeter is connected in parallel across the circuit element (resistance ) so that its inclusion in the circuit has negligible effect on total resistance and current flowing in yhe circuit A voltmeter has high resistance,if connected in series it will increase of circuit and reduce the current in the circuit
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.

If you have a circuit consisting of a battery and a wire What two factors determine the amount of current in the circuit?
The voltage of the battery, and the resistance of the circuit (including the resistance of the wire and the internal resistance of the battery).

How do you increase resistance?
Since resistance is the ratio of voltage to current, if the voltage is constant then increasing the resistance will result in a reduction in current.
In series circuit is currant change with change in resistance?
V=IR where V is voltage, I is current and R is resistance. You want to know what the current will be in a series circuit based on the resistance. You need to know the voltage as well as the resistance, gives you the equation as follows I=V/R So if you have 10 volts and a 1 ohm resistor, the current will be 10 amps. If you increase the resistor to 10 ohms, your current will then be 1 amp. In a parallel circuit, the resistance is equal to the sum of the inverse. For example. If I have two resistors of 2 ohms each in parallel, the equation would be 1/2 + 1/2 = 0.5 + 0.5 = 1 In that particular instance, your current would increase.
How are current and resistance related in a circuit?
The current between any two points in the circuit is the voltage between those two points divided by the resistance between the same points.
Is resistance in a series circuit equal to the largest resistor in the series?
No. The resistance in a series circuit is all the resistor values added together. eg. If two resistors were in a circuit, one was 10 ohms and the other was 30 ohms, the resistance in the circuit would be 30 ohms. Hope this helps!
Name two factors that increase peripheral resistance?
Peripheral resistance can be increased by an increase in blood volume and the constricting of blood vessels.
