HELP ASAP PLS Explain how an electric current can travel through conductive materials. Identify three different materials: one that is a good conductor, one that is semi-conductive, and one that is a good insulator. Explain why each material possesses its specific properties and suggest an application for its use in everyday life.

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?

The junction rule describes the conservation of which quantity? note that this rule applies only to circuits that are in a steady state.

Make a drawing of the electric field lines around a positive charge, then make a second drawing of the electric field lines around a negative charge.
