34. You put 9.0V DC across resistor R. and measure the current through it. With the same voltage across resistor R₂, you measure twice the current. What is the ratio R₁/R: ? O 1 O 1/2 O 4 02 35. How much current will flow through a 10-V battery with a 100-2 resistor connected across its terminals? O 1.0 A O 0.1 A O O A 1000 A 36. Doubling the voltage source connected to a resistor * decreases the current passing through the resistor in half decreases the current passing through the resistor to zero doubles the current passing through the resistor quadruples the current passing through the resistor

Resistivity

Resistivity is a characteristic property of the conductor’s material that measures the extent to which the material opposes the flow of current. It is denoted by the Greek letter “rho”. Electrical resistivity, also known as specific resistance, depends on the nature of the material of the conductor and is unaffected by its dimensions.
