E

I R

You can use the EIR triangle to help remember

the three versions of Ohm's Law.

Write down E, I and R in a triangle like the one above.

To calculate voltage, E: put your finger over E,

this leaves you with I R, so the equation is E = I × R

To calculate current, I: put your finger over I,

this leaves you with E over R, so the equation is I = E/R

To calculate resistance, R: put your finger over R,

this leaves you with E over I, so the equation is R = E/I

(V is sometimes used for Volts, but E is the correct mathematical term)

The Award was designed and constructed by Ray McCabe EI7AHB and presented by him to EIØNDR in 1991, subject to the following conditions:

It
would
be
administered by North Dublin Radio Club and may be awarded on an
annual basis in recognition of services provided to Amateur Radio and
dedicated to the memory of the late WILLIE J BARRON – Call-sign EI6BUB

It will be known as the W J BARRON MEMORIAL AWARD and awarded by majority consensus of the EIØNDR Committee at each annual AGM. It may not be awarded in any year unless the level of work or contribution under consideration is felt worthy and qualifying in terms of advancing the interests of the hobby within the world of Amateur Radio, be it at Club, National or International level.

The award will be inscribed annually and returned to EIØNDR at the end of each award period. A record of the reasons meriting presentation will be written into the annual Minutes of each AGM at which the Award is granted.
