How do I download PhET simulation?

Download the PhET CD-ROM Distribution archive onto your computer (280 MB). Extract the contents of the archive (on most operating systems, this is done by double-clicking the downloaded file). Copy all the files to the CD-ROM. Please remember to periodically check for updated versions of the PhET simulations .

How do I calculate resistance?

If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm’s Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.

Is voltage the same in parallel?

A parallel circuit has two or more paths for current to flow through. Voltage is the same across each component of the parallel circuit. The sum of the currents through each path is equal to the total current that flows from the source.

What is potential difference in a circuit?

The voltage difference between any two points in a circuit is known as Potential Difference and it is this potential difference which makes current flow. Unlike current which flows around a closed electrical circuit in the form of electrical charge, potential difference does not move or flow it is applied.

What does a resistor do in a circuit?

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits , resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.

Is current the same in series?

In a series circuit, the current is the same at each resistor. If the light bulbs are identical , then the resistance is the same for each resistor. The voltage boost in the battery will be equal to the sum of the voltage drops across all three resistors.

What does a fuse do in a circuit?

The fuse breaks the circuit if a fault in an appliance causes too much current to flow. This protects the wiring and the appliance if something goes wrong. The fuse contains a piece of wire that melts easily. If the current going through the fuse is too great, the wire heats up until it melts and breaks the circuit .

How do you calculate current?

Ohms Law and Power To find the Voltage, ( V ) [ V = I x R ] V (volts) = I (amps) x R (Ω) To find the Current , ( I ) [ I = V ÷ R ] I (amps) = V (volts) ÷ R (Ω) To find the Resistance, ( R ) [ R = V ÷ I ] R (Ω) = V (volts) ÷ I (amps) To find the Power (P) [ P = V x I ] P (watts) = V (volts) x I (amps)
