Presentation transcript:

Rate at which electric charge passes a given point 2 types DC which is direct current AC which is alternating current amount of work needed to move a charge between Two points. There is a direct relationship between voltage and current. Higher voltage = Higher current Resistance is opposition to electric current or the passing Of a charge between two points. Inverse relationship between resistance and voltage Higher resistance = lower voltage 4 affects or influences on resistance Composition metals are less resistant Temperature Thickness Length

#9 skip create a skit

X are selected For more or Higher Resistance To flow of charge x x x

14 Resistance is defined as opposing the flow of electric current 14 Resistance is defined as opposing the flow of electric current. Electric current is defined as the rate of passing of a charge between two points. A thinner and longer wire will increase the Resistance, opposition to the flow of the current, so there might not be enough electrical Energy flowing between points to get the electrical device to operate.

Inverse relationship exist Between resistance and current Direct relationship between voltage and current

9 Because there is less Resistance in wire composed of copper, the copper wire will have a higher current Than the geranium wire 10 There is a direct relationship between voltage and current so Higher voltage means higher current if equal resistance.
