1. Draw a simple circuit with a battery supplying DC cu
ent to a resistor. Label where the
anode and cathodes are.
2. Calculate the cu
ent through the circuit with a 12.0 V battery for the following resistors:
R = 12.0 Ω R = 6.0 Ω R = 3.0 Ω

1. Refer to figure 1 and table 22.1. Calculate the resistivity and conductivity of a tissue
sample, held at room temperature, that has a cross-sectional area of 2.50x10-4 m2.
Based on these results, what type of tissue is this?
