Answer 10

has 0 voltage and 0 resistance

Question 11

open circuit

Answer 11

has 0 current at all times, infinite resistance

Question 12

resistors. ..
- ideal resistors obey …..law
- ohms law….the voltage across a resistor is ……. ….. to the current through it.
- v=………[only when i is flowing from the plus of the v to the minus of the v]
- this implies that in……..current flows from a higher………..to a ………potential

Answer 12

Ohm’s law, directly proportional,ri, resistors, potential, lower.

Question 13

power is the …. of current and ….. and is the …….of energy ….

Answer 13

product, voltage, rate, transfer

Question 14

Elements are in series when

Answer 14

-chain-connected or
connected sequentially, end to end
-elements in series split voltage not current.

Question 15

Kirchhoff’s Current Law (KCL)

Answer 15

the algebraic sum of the currents flowing

in/out of any node must equal zero

Kirchhoff’s Voltage Law

Answer 16

the algebraic sum
of the voltages around any closed loop in a circuit is equal
to zero
