Answer:
Option A
Solution:
As per the question:
Initially, voltage is 
Current is 'I' A
Length of the wire is L
Now,
We know that:
(1)
where
A = Cross sectional area of the wire
From eqn (1), if other things are taken to be constant, then
R ∝ L (2)
Thus
When the wire is cut into two reducing the length to 
Resistance, R' = 
Now, when these wires are connected as described, the connection is in parallel, therefore, the equivalent resistance of the two wires:
Now, from Ohm's law:
Since, according to the question voltage is constant, thus
I ∝ 
I ∝ 
Thus
I becomes 4I
Answer:
shorted
Explanation:
A diode is a device that passes current much better in one direction than in the reverse direction.
<h3>Ohmmeter test</h3>
Conceptually, an ohmmeter applies a voltage to the device under test and reports the current through the device on a scale calibrated in ohms. It typically has a low enough open-circuit voltage, and a high enough internal resistance so as to avoid damage to parts under test.
A "continuity" tester may have an open-circuit voltage of a few tens of millivolts and/or a short-circuit current of a few microamps, so as to properly detect continuity and avoid contact damage in "dry" circuits. Such a tester is virtually useless for diode testing.
An ohmmeter suitable for diode testing will generally have an open-circuit voltage of a few volts, and a short-circuit current of a few milliamps. When such a meter is used to test a diode, it will indicate a few kilohms (or less) in the "forward" direction, and several 10s or 100s of megohms in the reverse direction.
<h3>Low-resistance readings</h3>
If the "forward" resistance reading is unusually low (a few ohms), the diode may be <em>damaged</em>. If both forward and reverse readings are unusually low, the diode my be considered to be <em>shorted</em>.
