b. 2 Ohms
c. 1 Ohm
d. Cannot be calculated
Answers
Answer:
2ohms
Explanation:
v=6 volts
current(I)=3 amp
resistance(r)=?
from ohms law v=IR
R=V/I
R=6/3=2ohms

Answer:
Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. Introducing the constant of proportionality, the resistance, we arrive at the usual mathematical equation that describes this relationship: I=
R
V
,
where, I is the current through the conductor in units of amperes, V is the potential difference measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms.
Therefore, R=V/I.
R=

Explanation:
24/12=2 amps. current=-amperes.
There are basically three types of Ohm's law formulas or equations.
...
They are;
I = V / R.
V = IR.
R = V / R.How much current would flow through a circuit that has 1000 ohms of resistance if powered by 1.5 volts? I-V 1.5V 0.016A . 2.Microscopically, Ohm's law is a statement about how application of an electric field to a conducting material leads to an electric current: J ⃗ = σ E ⃗ . ... In the above equation, σ is a constant called the conductivity of a material, E is the applied electric field, and J is the electric current density at a point.
