Answer:
60 Ω
Explanation:
R(com) = 15 Ω
1/R(com) = 1/R1 + 1/R2 + 1/R3 ..... + 1/Rn
1/15 = 1/20 + 1/R2
1/R2 = 1/15 - 1/20
1/R2 = (4 - 3) / 60
1/R2 = 1/60
R2 = 60 Ω
así, la combinada de resistencia necesaria es 60 Ω
Ionic solutes are considered strong electrolytes. What does this mean for the conductivity of the solution?
A) Strong electrolytes dissolve and completely dissociate in water providing charged ions to conduct electricity.
B) Strong electrolytes dissolve and do not dissociate in water providing no charged ions to conduct electricity.
C) Being a strong electrolyte refers the type of bonding and has no bearing on conducting electricity.
D) Strong electrolytes do not dissolve in water and can not conduct electricity.
ANSWER:
A) Strong electrolytes dissolve and completely dissociate in water providing charged ions to conduct electricity.
Answer:
4 A
Explanation:
V = IR, where V=voltage, I=current, R=resistance. This is Ohm's Law. (remember that for units V = volts, Ω = ohms, A = amperes.)
V = IR
12 V = I * 3 Ω
12/3 = I
<u>I = 4 A</u>
