1- What is Resistance? A measure of how strong an object or material impedes the current produced by a potential difference

2- What controls electric current? Resistance and protectors like a fuse, circuit breakers, and surge protectors can easily control electric currents in a circuit.

2-Lenght \ Cross-sectional area\Temperature \ Material .
3-is device designed to have a specific resistance .
4-I can be changed by varying V,R

# data[].attributes.body
1- Resistance is the how an objects allows current produced by potential difference will flow.
2- Affect resistance
length increase R increase
cross section are decrease R increase
Temperature increase R increase
3- A device produced to have specific resistance
4- Current can change by
- Changing potential difference ( I increase)
- changing resistance (I decrease )
- or changing both
5- A device that allows continues variation rather than step by step. ( resistor with a switch )

# data[].attributes.body
1- Resistance is a measure of the opposition to current flow in an electrical circuit.
2- Length,  Resistance increases as length increases
Cross- sectional area, resistance increases as the cross-sectional area decreases
Temperature, resistance usually increases as temperature
Material, Keeping length, cross sectional area, and temperature constant resistance varies with the material
3- resistor is a device designed to have a specific resistance
5- circuit breakers switches

# data[].attributes.body
1- Resistance is defined as potential difference divided by current .

2- Length - cross sectional area - temperature - material

3- is a device designed to have a specific resistance .

4- we can control the current by changing the value of potential or potential different .
